What? Broken

My forgetter's getting better But my rememberer is broke to you that may seem funny but, to me, that is no joke For when I'm "here" I'm wondering If I really should be "there" And, when I try to think it through, I haven't got a prayer! Oft' times I walk into a room, say, "What am I here for?" I rack my brain, but all in vain A zero is my score. At times I put something away Where it is safe, but, Gee! The person it is safest from Is, generally, me! When shopping I may see someone, say "Hi" and have a chat, Then, when the person walks away I ask myself, "who's that?" Yes, my forgetter's getting better While my rememberer is broke, And it's driving me plumb crazy And that isn't any joke.
