Keys

I have been making myself crazy for days searching for my keys. Sunday, I took some things to school and left them. I locked the building up, went to the grocery story and then I don't remember much until Sunday evening when I was grading papers and updated grades. This afternoon I was looking in the trash, had an AH HA moment went and looked on the dining room table where I left my mess from grading...and Viola there they were on top of the pile....so what makes me blackout like that? hormones?
