I was at the national conference for my field in November. I was at a dinner, and my advisor introduced me a professor who I'm actually using for my thesis work and has connections with a program I'm interested in. As we're talking, he mentions that he's taking a new direction looking at religion in contexts of political communication. He's a professor at Utah, so I asked if he had done anything with the Mormon community, patting myself on the back for and interesting segue. Except, he didn't take the bait. He just said no and stared at me. I hadn't planned on that, so we stared at each other for a good 30 seconds. Then I apologized for being so awkward. I wanted to melt into the floor for the rest of the night.
I've since made up for it, and got invited to write a paper with him.
