I was in my local Wal-Mart shopping for Halloween candy for tonight's "Trunk-Or-Treat" when I saw him at the other end of the aisle, and I instantly moved to the next aisle to avoid him. He's not a horrible person, he just creeps me out and I wasn't in the mood to be superficially social. As I moved through the chaos we came face to face and I couldn't avoid him without being rude, so I said hello.
Me: "Hey, how are you?"
Weird guy: "Good, how 'bout you?"
M: "Fine. Are you shopping for a Halloween costume?"
WG: "Oh no. They don't have the costume that I want."
M: [against my better judgment] "Oh? And what's that?"
WG: "A teletubby with a chainsaw."
I raised my eyebrows in mock interest, but said nothing.
WG: "You know, because they're supposed to be nice. That's why it's funny."
M: "OK then. Good luck with that." You freak!
