Can any parents help me out, im so confused right now- even an older person, maybe?

your parents make a good argument, if you have one set of earrings you don't need another set. PLUS you get to go to spain for ten days, that is more than wonderful. On the other hand you don't need to be like your older sibling(s) because maybe your parents don't want you to act like them. But i have been in almost the same position as you are where i wanted do be like them,act like them, and do the same things, but before you do anything think to yourself and ask, how will this make my life better, and how will this effect me, then look at it through your parents eyes. then you will know the right answer for you.

IMO, yes,I'm older, you are the youngest and therefore the one they trying to hold onto, maybe? It kinda' worked the other way at my house as my older kids broke ground for the youngest. They say he gets away with a lot more than they did. Or they may be frustrated about something else, like money? Are they looking at college tuition, multiple cars and insurance AND a trip to Spain? I know you feel entitled to what the older kids have gotten but the economy is so screwed right now, that might be part of the problem. It sounds like you are doing the right things so hang in there and know they love you, even if you feel so frustrated with them.

What does having a permit have to do with any of this??

It's you. If they aren't telling you why, it means that they just don't like it and can't adequately explain why. I know why I wouldn't want you to get your ears pierced twice: it looks low-class. Now every female who reads this and has double-pierced ears is going to make nasty comments, but it doesn't change the fact that double-pierced ears go right along with skin that's too tan, hair that's too blonde, lipstick that's too pale, and clothes that are too tight. I'm sure that your parents see you as someone who will be successful some day, in a job where double-pierced ears will give the wrong impression of who you have become, and they're permanent and public, so instead of looking cultured, sophisticated, and professional, you will look a bit cheap. When you turn 21, if you still want double-pierced ears, get them then. Until then, just accept that there are some things you can whine and wheedle for and some things you should just wait for.

i was 4 when i got my ears pierced and i got my cartilage pierced when i was 11 and im the youngest and you can just go 2 the mall and get them pierced your self if u really want 2

The thing with parents is they don't HAVE to tell us why. I know it is frustrating but there isn't much else you can do. I would just put the issue aside for now until after your trip. When you come back just sit them down and explain how you feel in a calm manner. Tell them you are responsible enough to go to Spain, to drive a car, to do this and that and you don't understand why they think you aren't responsible enough to have your ears pierced. Hopefully, that will work. Just try to put it out of your mind for now. Just go to Spain and have fun and just chalk the matter up to parents are just weird like that. Maybe they think of you as their baby, their youngest and they don't like the fact that you want to do more mature things. Give it some time. They will come around. Good luck!
