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 those weekends 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
