I know where it is. It's on a flat surface.
Yes, my DH is guilty of this. Any flat surface will do. Sometimes the window sill in the kitchen, which drives me mad.
I always put my car keys in the same place. Why wouldn't you. My DH has a corner in the kitchen where I dump all the stuff he leaves lying around. He still loses stuff
On the other hand, I have often gone around looking for my glasses only to find them on my head
