When I'm tired, my sufferance of fools goes way down. My sarcasm goes way up.

After several hours of Christmas shopping this afternoon, I walked into Restoration Hardware, put down my heavy bag of gifts, and collapse into a very comfortable leather armchair. I laid my head back and sighed.

Assistant: Can I help you sir?
Me: Yeah, be a love and fetch me a cup of tea will you. Milk, no sugar.
