Oh, I would love to be able to sing, but I can't carry a tune in a bucket.
But, I can make or fix pretty much anything I set my mind to.

IBrakeforPastry - that is something that happens to me too. The word I need just disappears from my brain. It will have been there, just waiting it's turn, then when I need it, it's gone - then I'm left saying things like, you know, that round thing you make soup in.
