the man who lives at my work

Or rather outside of my office, next to the trash bin. This appears to be his bedroom since he's usually sleeping. When he's awake he never asks for anything. He never talks at all. He never even seems to notice that there's anyone else around. He's just always there. Yesterday, every time we went into or out of our office he was standing and staring off into the distance moving his right hand in a round and then out motion. If he'd have incorporated other movements I would've thought he'd taken up tai chi. And so it's another day and he's asleep and I have no idea what he was doing.
