Do you believe teenagers can fall in love?

Alright, so today my very good friend told me she had with her boyfriend of a month, but they were in love. I didn't care that she had , because honestly who isn't having ? We are both only 15 if it matters. But i was more troubled by her saying they were in love. Maybe i'm just cynical, but i don't really believe that teenagers could fall in love, real true love. Do you believe teenagers can fall in love?
