I don't know. One time I joined a game, and I had plenty of reasons to join the party, but the DM started RPing a really rude character, and it's like his method of getting me to join the party was to be a huge asshole to me? I just didn't pick up on it, and when I finally gave my character an ass-pull reason to join (that I could do some good if I tagged along) the DM was like "jeez, finally" and it sucked.

Like, if I'm playing a level 1 wizard, and the DM tells me I'm gonna die if I enter the conflict, it's not really my backstory's fault that I don't jump into the fray. Sometimes you're dealing with an inexperienced DM that expects you to metagame your way into the party. I genuinely thought he was on the verge of giving me the opportunity to convince the party to run away from the dragon, not stay and fight it.
