Disclaimer: I DON'T OWN TAYLOR SWIFT SONGS OR HARRY POTTER! I just own this xDIt's like a parody THIS IS ALL NEXT GEN BTW! (So Lily's Lily Luna Potter :D )

You take a deep breath and you walk through the doors
Its the morning of your very first day
you say hi to your friends you ain't seen in a while
Try and stay out of everybody's way
It's your fifth year and you're gonna be here
for the next two years in this school hoping one of those seventh year boys will wink at you and say
you know I haven't seen you around, before

Cause when you're fifteen and somebody tells you they love you
you're gonna believe them
and when you're fifteen
feeling like there nothing to figure out
well count to ten, take it in
this is life before who you're gonna be
fifteen

You sit in class next to a redhead named Lily
and soon enough you're best friends
laughing at the other girls who think they're so cool
we'll be out of here as soon as we can
and then you're on your very first date and he's got a broom
and you're feeling like flying
and Lily's waiting up and you think he's the one
and you're dancing round your room when the night end
when the night ends

Cause when you're fifteen and somebody tell you they love you
you're gonna believe them
when you're fifteen and your first kiss
makes your head spin round but
in your life you'll do greater than dating the boy on the Quiddich team
but I didn't know it at fifteen

When all you wanted was to be wanted
wish you could go back and tell yourself what you know now
Back then I swore I was gonna marry him someday
but I realized some bigger dreams of mine

And Lily gave everything she had to a boy
who changed his mind and we both cried

Cause when you're fifteen and somebody tells you they love you
you're gonna believe them
and when you're fifteen, don't forget to look before you fall
I've found that time can heal most anything
and you just might find who you're supposed to be
I didn't know who I was supposed to be at fifteen

Youre very first day
take a deep breath girl
take a deep breath as you walk through those doors.
