where have you been?

I tend to randomly loose things from the tip of my nose from the places they are surely safe and even visible. Places like desks and open shelves and even floor. It happens almost all the time and starts to get on my nerves quite bad as well as makes me simply desperate and confused.. this time it was my tooth-brush.. I came home in the morning after the night spent at me friends house, open the bag, take out the tooth-brush [which I actually didn't even use] and place it on my desk while thinking "I should put it in it's place in the bathroom but... I'll do that later" now in the evening when I am going to take it for use I can not find it anywhere. It has simply disappeared in thin air. I check the whole desk even under and above it, my bag two or three times but it is nowhere to be found. With given up hopes I just take one of my old brushes and use it. Go back to my room take my tool box from me closet cause I had a plan how to make my broken headphones usable again... open the tool box and what do I find there? Between all kinda tools and gears there it lies, my tooth-brush.
