What is it?
Do you ever see something lying on the floor that you just don't know what it is but it must be something important? Like a screw, it must have fallen out of something, maybe it was holding something together. Or a plastic door that looks like it came off the battery compartment of a remote control? What do you do with these things? I put all of them on a shelf in my bedroom. Then when I notice the leg on the coffee table is loose or the downstairs TV remote is missing batteries, I know where the part is!
