Whenever you're speaking to somebody who is dominating the conversation, focus on their chin or ear. Look slightly concerned.

When I was a corrections officer we had a guy who worked with us who was kind of mean to everyone, and he was computer illiterate. We took a screenshot of his desktop and moved all of his icons off of it so it looked legit but nothing worked. It took him an hour before he finally called IT and they figured it out pretty quickly. He wouldn’t talk to any of us for about a week. -justneedadvice87

The movie theater in my town is usually mostly empty. There's been a couple of times when I've come in to get seated and there's literally only one other person in my auditorium. There's an evil part of me that wants to just go sit right next to them. Not illegal, but it should be. -matt314159
