I'm not going to lie to you and say it didn't hurt
to see you with someone new you were wearing my old blue shirt
But that didn't kill me until we said "Hello"
And I became someone you used to know
Like a friend Like a fool Like some guy you knew in school
Didn't we love? Didn't we share? Or don't you even care?
I know we said we were through but I never knew how quickly I would go
From someone you love to someone you used to know
Bet you didn't tell him about our weekend at the coast
or how we used to argue 'bout who loved who the most
I guess I won that one 'cause I still need you so
But to you I'm just someone you used to know
Like a friend Like a fool Like some guy you knew in school
Didn't we love? Didn't we share? Or don't you even care?
I know we said we were through but I never knew how quickly I would go
From someone you love to someone you used to know (2x)
