Why do some old people hate teenagers?

I'm guesing because they forget they were teenagers once, OR perhasp the teenagers they have had occasion to encounter RECENTLY can kind of be rude and ask non-sensical questions like "can you borrow me a cigarette?" (sort of like the asker is doing the giver a favor)

I read all you said and can see you are trying to find positive roads to understanding. At any age that is a sign of kindness and someone who wants productive outcomes so good luck. Adults all need to show good manners at any age and patience with people is a sign of maturity.Remember that these people may have witnessed very bad behaviour of people that look just like you and so as a defence mechanism people do judge at face value. I expected to move into middle age and find wise piers all around me,gentle and giving...This has not quite worked out as expected. There is good and bad all around us.Keep an open mind to ideas and people as you get older and accept that communication and manners are something we all have to work on every day.

I'm 70 and I am not offended. People of my generation were taught that good manners mattered and it became instinctive to give up our bus seats to older people or ladies. Good manners is the formalisation of consideration and that aspect of our lives has, sadly, largely disappeared I don't think that anyone has found a way of reminding people of their manners in an unoffensive way and I have to say that it is true that one is more likely to be met by aggression now than I would have expected in my youth. I am 17 and trapped in the body of a 70 year old - not a nice place to be when you see the total lack of restraints placed on our young people now. In my experience, the old are not always wiser, and the young now have the chance to better educated than we were but seem unwilling to take advantage of what we would have loved. I'm sorry that you were offended and I'm also sorry that the old person on the bus was offended. If either of you had responded by talking to the other in a friendly and considerate manner, each would have learned from the other. I accept that the young must be allowed to be young, but please accept that the elderly must be allowed to be elderly. We old folk are envious of the fact that you are not going to have to leave school at 14 or 15 as we did, that you have money and possessions of which we could not even dream and access to a standard of life which was beyond our imagining. But most of all, of course, we envy and resent your youth and the fact that you have a future life to look forward to. Be gentle with us, please.

Jealous of our youth, especially older women they hate with all their might younger females. Older males are not like that, because men are like a fine wine the older the better. But is not the same with women, because they are treated like moldy cheese.I mean nobody wants to have sex with a 60+ year old lady. But a a 60+ year old guy is kind of hot.

Jealousy, plain and simple. Old people (most of all the baby boomers) are fulled with regret for all the time they wasted and did nothing, they wish to be young again and to be able to do the things that they never had the chance to do, they see young people doing the same mistakes they did or doing what they never dreamed of and it makes them very angry.

"A couple of old people came onto the bus and gave my friend a really dirty look because she was listening to music quite loud. Then she said to me "Are you going to sit there being gormless or are you going to move and let me sit down?" " This couple is not that good themselves. They don't have whatever they expect from teenagers & it's called manners. They shouldn't treat all teenagers the same because not all of them are rude & wild. They should know better and you should know they are not better than you, they are worst (because they're older but can't judge people right) Old people hate teenagers because they have reasons and 1 of their reasons is that riot. Teenagers give themselves a bad name so it's not surprise when old people look at you like that. Although it's normal but they should know not all teenagers are bad. You have to prove to them otherwise so that they can change their look with you. Older people are smarter & wiser with life because they almost done with theirs. The more experience you have in life, the wiser you are with it. You teenagers are smarter & wiser in different areas (like technology, for example). That couple on the bus gave you that look because you hang out with friend who has no manner. She shouldn't turn on the music too loud (to respect other people around). Although you're not your friend but they think if you hang out with that kind of kid, you might be as well like her

The answer to your question is in your own discussion. Some people unfairly lump teenagers or old people or an ethnic group into a one-size-fits-all category in their minds. It's a prejudice. There is little you can do to alter the preconceived unfavorable opinions these older people form about teenagers. The one good thing for teenagers is it is a temporary situation for you will inevitably grow up and no longer be a teen in a few years. Meanwhile,recognize it for what it is and try to apply what you don't like about the situation to an understanding of those who suffer prejudices that they cannot outgrow.

if they be really old and frail they are scared they do not think as quick and become very set in their ways and their attitude suffers hence every teenager is a trouble maker

We're a new generation and life for us is very different from teenage life back in the old people's time. Some old people can be quite rude because they probably can't accept how fast this world is developing and they think all teenagers should be catching sticklebacks in the stream, but this is not the case. Most old people I've come across are friendly after I've given them a smile.. oh yeah, the one important thing: smile! Oldies think teenagers are grumpy but if you smile they will be surprised. However if an oldie is ever unacceptably rude then just ignore them. That's what I do.
