Some dude just came to the door.

"I'm from MORI. We're doing a survey about travel. Could you..."

"I'm afraid I don't really have time for that now."

"Okay, when would be a good time?"

"...(shit)"

Now he's coming back at 6, when I doubt I'll be home. What I should have said was "I'm not interested in doing surveys. He caught me by surprise, dammit!
