well.. im not from US.. but i want to answer for my country.. here.. teens today have too many freedom... ppl around 13 or 14 can go to night clubs just cuz they can give some money to the guard to let them in.. or using fake ids..(btw.. some teens appear to be older and they are dumb kids of 13) they begin becoming rebel at early teens also.. even from 12 yrs old..
in my case.. i would like to go to night clubs and stuff, but im 16.. i dont do those stuff of fake id or bribe the guard.. cuz i just believe its wrong and dishonest.. bottom line.. in many countries, US and many other places, teens have way too much freedom nowadays.. i believe this is wrong, cuz they can get in problems, or suffer a tragedy, like pregnancy at teenage years(girls) or guys getting into prison
on the driving stuff.. here 16 yr olds can have a permit to drive from 6 am to 9 pm.. im getting mine on friday =D.. thats completely legal here..
relationship status.. even from early teens, they feel true love, have sex and everything, and many times relationships at this age is to literally "waste some time"
