I used to know a guy who was really, really into fishing. Good on him. It’s great to have a passion. But what made me feel sorry for him was that it was his only passion.
He was really hard to talk to, because fishing was his only topic, and if you weren’t into it (and I’m not), conversations with him quickly became extremely dull. If you tried to discuss current events, he had nothing to contribute. If you tried to be playful or in any way abstract or imaginative, he would give you a blank stare. Talking to this guy was a study in awkward silences. I used to think, “I know you’re in there… somewhere.”
I much prefer the company of more well-rounded individuals; people who are curious about the wider world. I enjoy not being able to predict the direction a chat will take. I like to banter. In that context, I might even enjoy talking about your piscatorial pursuits.
If you want more people to delight in your company, make an effort to expand your horizons. Become a bit more three-dimensional. Depth is important, as well as length and width.
