We're talking about someone at the game table. They very likely had no plans, BECAUSE THEY'RE AT A GAME. And said significant other likely had plans as well.
Not someone. A specific person. This isn't a hypothetical situation, this is something that actually happened.
Since he was able to call her and immediately go to a movie with her...no, she didn't have other plans. Stop making stuff up.
And then the character dies and rather than watch and hang out, the player would rather leave. Watching the game is apparently so horrible they'd rather walk away than spend a minute there.
Again, stop making stuff up. Everything you just stated is pure BS. You aren't psychic, you aren't a mind reader. You are projecting your personal issues and biases onto a situation you were not involved in.
It was a choice between watching people play after he was no longer allowed to participate (and knew for a fact he wouldn't be able to rejoin them) and spending time with his girlfriend.
It's not that the game was horrible, it's that he had something better to do. This should not be a difficult concept. Hanging out with a group of guys pretending to be elves and dwarves is fun, but it's not the ultimate social activity. Some people also have relationships outside the gaming table.
Now, if they were double booked that's a different things. Or if they knew there was something else going on. Or if they were really behind at work and could barely justify gaming already.
But that's a pretty unlikely.
What
you would do in the situation isn't relevant. You weren't there. What
you think justifies leaving isn't relevant. This didn't happen to you.
As I've said numerous times already, this is a really stupid argument.
I cannot fathom why people are being so hostile about such a simple thing.
"I can no longer participate meaningfully here, but I can go spend time with my girlfriend and watch a movie. "
Seems like a really easy decision.
