Inkwell the cat hated being "locked" out of my room, and would yowl at the door if I closed it to get some privacy. One day I closed it to get work done - since Inkwell was in the habit of pushing my laptop off my lap. When I finally opened it, he sat in the doorway and glared at me, then reached a paw out and pulled the door shut. Due to some weirdness of air pressure, it slammed.
Inkwell was not amused by my hysterical laughter at his tantrum.
