Denial? Look, the "it's only a game" line is true to a point, but we're not talking about Uno or Battleship here. People have given up their Sunday afternoon and burned up some gas in order to show up for this campaign, and as the DM I'm putting in plenty of time and effort before the game trying to make it as good as possible. The frustration I feel isn't due to a loss of perspective. It may only be a game, but there's some investment on the part of everyone involved. And once again, I certainly had every impression that the guy appreciated that.
*Ring-ring!*
"Hello?"
"Hey Bob, what's up?"
"Hey Nate!"
"Listen, me and Ruth are going to go to Jimbo's bbq tomorrow, how about you?"

Scenario 1
"Oh, too bad, I got plans."
"Oh yeah? What's up?"
"I'm going to play D&D with some guys."
"D&D? Huh. Who else is going?"
"It's actually with a bunch of strangers I met on the Internet..."
"Uh, okay Bob."

Scenario 2
"Oh yeah? What time?"
"Prolly 2 PM, so we can eat a bit and have time to watch the game."
"Yeah, cool, I'll be there."

That's the denial I'm talking about: the refusal to admit -- even to one's self -- that one is about to do something very nerdy. Oh the shame, the heartfelt suffering, the cowardly retreat from reality and reason.
He can be rude to you if he doesn't admit that:
1/ your game is "real" (important); and/or
2/ you are "real" (important); and/or
3/ the whole hobby is "real" (important).
Anyway -- that's my story, and I'm stickin' to it, like a goatee on a bard.
