Can you believe it 13 year olds are talking about boyfriends?

I hear a lot of 13 year old girls talking about how they are dating and "LISTING" how many boyfriends they had i mean FOR CRYING OUT LOUD THEIR ONLY 13! i'm 19 and a half and as much as i did like boys back then i wasn't talking about dating and relationships instead i was conscentrating on my education. It seems like the youngsters of today are growing up way too fast! And i heard my friend (who's 18) tell me how a 10! year old had their own account on facebook ain't he too young for facebook? or am i just finding out something new? maybe i'm living in the past but i think teens are growing up way too fast!
