I understand what you're saying, but it's also considered common courtesy to politely accept when you've been told no. Rights actually have quite a bit to do with it, because forcing yourself into a situation when you have no right to do so is showing a lack of common courtesy. The two concepts are intertwined, as common courtesy tends to be determined by the rights of the individuals involved. The OP did tell him he wanted to play alone, and you're right that his response could have been made more polite by giving a specific reason, but I still consider the other guy's actions more offensive. At least according to the OP's version of the story, since the other guy apparently resorted to insults. Could there be another side to it? For sure, but until the other guy comes here and tells us (which isn't likely), we don't know anything about it. I'm inclined to believe the OP, simply because I've seen the same situation lots of times before. People love to feel entitled, even when they're unjustified. I'm not saying your assessment is completely wrong, but it takes a much larger leap of faith to argue for information we don't have than to argue for information that we have (and assume some degree of bias).
