Captain likes to sit next to me on the sofa when I work on my laptop. Mini the Wee decided that his proximity to me meant he was getting more attention than she was. So she stood on her hind legs against the sofa, making her just barely as tall as the sofa cushion, and barked at him. "AR AR AR AR!"
In response, Captain gave her a Kitty Glare of Death and bopped her head. So Mini dropped down to all fours, putting herself out of reach of the bopping paw, and resumed barking. "AR AR AR AR!"
After I stopped laughing, I picked the dog up and put her on the other side of me. That way, they could BOTH sit next to me on the sofa, and everyone was happy.
