Why do people always ume that teenagers can never really be in love??just adults?

omg i know!!!! its SO annoying. and the thing that makes it even more annoying is that you KNOW those exact adults who tell u stuff like that, were once teenagers in love. ugh! ha people are hypocrites. but yeah i totally get what ur saying because me & my boyfriend definitely love each other, but at the beginning of our relationship his parents decided to sit him down and TELL him that he wasnt in love with me and just had lust for me. well....we've been dating for over a year, have never had , but our relationship gets better every single day :) we proved them wrong! lol
