As a rule, most of teenagers in my country don't be allowed to do every thing or go everywhere they want,their parent set some rules for them an they should obey the rules, parents think if they set these rules for their children it shows their concerned about them, and they think these are inseparables of children's training, for example some teenagers don't be allowed to be out of home until midnight or don't be allowed to go to their friend's home, and such a these things...
but I think some of these rules can effect vice versa, and teenagers become rebellious...
by the way the majority of the parents in my country have some strange idea...
