Lyrics:

I ain't gonna lie to you
And say it didn't hurt
To see you with someone new
And you were wearing my old blue shirt
But it 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 loved to someone you used to know

Bet you didn't tell him about that weekend at the coast

Or how we used to argue about who loved who the most
Well, 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 loved to someone you used to know

Didn't we love, didn't we share
Or don't you even care
I know you said we were through
But I never knew how quickly I would go
From someone you loved to someone you used to know
I'm not someone you love
I'm someone you used to know
