At work, there is a guy who is basically a loser. He has zero friends, everyone makes fun of him, and he just takes it. When he fights back, he just makes things worse. I'm basically the only person in our workplace that's nice to him. I don't make fun of him behind his back, and when I do I laugh with him rather than at him. I laugh at his jokes whether they're funny or not. Like I said, I'm the only one that's nice to him. He's 20, in college, and still living with his parents. He never goes out or anything like that. I invite him out for pool with some friends of mine. We all have a good time, or so I thought. The other day at work, only a few days after we went out for pool, he told me that he "wanted to beat the f*ck out of me." Me, the only guy that's nice to him. And he wasn't even joking. I'm not concerned, as I'm confident I could take him in a fight. But I'd rather not get involved in a fight. I just think it's funny that of all the people he picks to start stuff with, he picks the only person that's been nice to him.
