I'm working over-time right now, and since I can do some stuff from home, I work a typical work-day and then do some work at home on the computer. Atlas thinks that when I'm home it means I want to play with him, so while I'm trying to get work done on my computer, he either brings me a toy so I'll play with him, or he flings himself onto my lap.
Yesterday I decided I needed some quiet, so I put him out in the hall and closed the door. Immediately, I see just the tip of his nose and one paw sticking under my door.
About a half hour passes and he's still there, waiting... Finally I feel guilty enough and open the door, and he flings himself on my lap and starts licking me.
