♪ It's strange to think the songs we used to sing The smiles, the flowers, everything is gone Yesterday I found out about you Even now just looking at you feels wrong You say that you'd take it all back Give it one chance It was a moment of weakness And you said yes You should've said no You should've gone home You should've thought twice Before you let it all go You should've known that word But what you did with her Gave back to me And I should've been there In the back of your mind I shouldn't be asking myself why You shouldn't be begging for forgiveness At my feet You should've said no Baby and you might still have me ♪ You can see that I've been crying Baby you know all the right things to say But do you honestly expect me to believe We could ever be the same You say that the past is the past You need one chance It was a moment of weakness And you said yes You should've said no You should've gone home You should've thought twice Before you let it all go You should've known that word But what you did with her Gave back to me And I should've been there In the back of your mind I shouldn't be asking myself why You shouldn't be begging for forgiveness At my feet You should've said no You should've said no Baby and you might still have me Oh ♪ I can't resist Before you go tell me this Was it worth it Was she worth this No No, no, no No You should've said no You should've gone home You should've thought twice Before you let it all go You should've known that word But what you did with her Gave back to me And I should've been there In the back of your mind I shouldn't be asking myself why You shouldn't be begging for forgiveness At my feet You should've said no Baby and you might still have me ♪
