Nevermind the reason, you may never know   Blame it on the seasons, they come and go   Blame it on the weather, something in the wind   Blame it on whatever, it might have been      You can say, you know what happened   You can say, that I was wrong   You can say, most anything you want to   You can say, I just say so long, so long, so long      Say it doesn't matter, say it's all for fun   Nevermind the laughter, that doesn't come   Tell yourself you hate me, tell us all your side   Tell your friends I'm crazy, it'll save your pride      You can say, you know what happened   You can say, that I was wrong   You can say, most anything you want to   You can say, I just say so long, so long, so long      So long, so long, so long I just say so long      Call it fact or fiction, blame it all on me   Speak of your conviction in destiny   Say it's not important, you can swear it's all a game   Call it fame or fortune, but it's all the same      You can say, you know what happened   You can say, that I was wrong   You can say, most anything you want to   You can say, I just say so long   So long, I just say so long      (You can say you know what happened)   You can say that I was wrong   You can say most anything you want to   You can say, you can say, you can say   I just say so long      (You can say you know what happened)   I just say so long   (You can say you know what happened)   I been wrong before   (You can say you know what happened)   Does it really matter, oh   You can say you know what happened
