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

If you didn't tell him about those weekends at the coast
Or how we use 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 we 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
