i need to know why

wait 20 years and maybe you will understand... LOL

if you're 16 then you need to understand that i love you.

My guess is that your a male,and that your young,around 15-16.Perhaps you have a girl that you like that is into older guys,or is dating an older guy.Well,heres the answer.Because the majority of girls will always be into an older guy.A 15 yr old girl see's 15 yr old boys,and thinks: all they know is PS2,and cartoons.While they look at a 20 yr old,and think: He's got a job,car,and a future planned out.hes got money,hes older looking,thus having a more bigger appearance.

yeah if you're a dude i totally retract that.

though often times the older guy has some shady motives, there are situations in which the man just knows that this younger girl is the one for him.
now, if she's not an adult, he oughtta keep it kosher. if she is an adult, hey.. that sucks. you'll get older too someday.
