Is teenage life in madrid really like this?

It normal that a boy say that but usually the girl don't say nothing or say something bad about the boy. About drinking, yes almost everyone tried alcohol when there are underage,normally with the consent of their parent. Some teenagers drink every weekends, usually without the consent of their parent. I remember to be 5 and my father letting me to drink a sip of a mild liqueur, but i didn't start to drink outside of home until i was 18. About going out, yes, some parent let their teenager sons and daughter to go out one or two night per week, other parents don't. About to get a new girl each, or he is handsome or he is exaggerating.

It's most likely a translation/culture issue. In Spain (via espanol) when people greet others (especially senoritas) the literal translation of such phrases as "hasta la vista" means in English "I can't wait to see your beautiful face again". It is a very personal language, and so is the culture. When meeting a woman you usually will kiss them on the cheek twice.
