I’ve never come across people like this in the real world, but online? Most certainly.
I know very few people in real life that want to discuss anything related to Star Wars.
Yesterday I walked back into my work area and one of my coworkers was saying he’d just seen TFA. My other coworkers saw me coming and said “Oh, there’s Drew, he can talk to you about Star Wars.” “I don’t need to talk about it in that much detail though,” he replied.
I’m known, and a few of my coworkers at least care about Star Wars a little.
