I Should Know By Now [Original]

All the things I've ever done Is focused on nothing but saying, "I've had enough!" I should know by now! I should know by now! And, all these lives have changed, radically And, every moment I've lived has been through this agony I should know by now! I should've known! I should know by now! I should know by now! I should've known! I should know by now! I should know by now! I should know by now! I should know by now! All my friends have been long gone And, before my master could sing or write a song, I should know by now! I should know by now! What's he doing with all the stuff? He's supposed to have some more fun I should know by now! I should know by now! I should've known! I should know by now! I should know by now! I should've known! I should know by now! I should know by now! I should know by now! I should know by now! Let's go! I should know by now! I should know by now! I should know by now! I should know by now! I should've known! I should know by now! I should know by now! I should've known! I should know by now! I should know by now! I should know by now! I should know by now! I should know by now!
