First gamer that annoyed the hell out of you? He was a nagging hanger-on and friend of our DM. When I first met him, he sat next to me and annoyed me so much, I stood up, grabbed his hat and flung it across the room. He thought it was funny and I was furious.
I was immature and he wanted attention.
I understand him much better now.
I wish I had handled it better.
Things got so bad, we eventually told our DM it's him or us. For awhile, he chose him. It wasn't pretty and I regret the whole episode. When a hobby is causing that much stress and conflict, take a break.
Eventually, I learned that gaming with a fun and healthy group was better than just gaming. I always wanted to game with "friends" and it took me a long time to see that most of the people at my table were "gaming buddies" back then. But I have one life long friendship from those days, so it was well worth it.
