If they сказал(-а) Ты are too mature, they probably didnt mean it in a positive way. Its a good thing to be responsible, but Ты are only going to be 14 once so live it. Try to find a good ballance.
Mature is a good thing...it means Ты are very respective and polite in public...that doesn't mean Ты can't have your own since of style.....just be who u r and you'll do just fine! Don't be stressed by it.... p.s Guy's like girls who are mature....more intelligent conversations and bantering...witty responses..trust me..I get along great with guys because I am who i am!
