when i didn’t want to be rude

So I’m part of this group, right? (It’s for a con next year… celebration-related)
Well, I was asked to be one of the ‘main’ characters for the photoshoot. I thought this would be really cool. The group accepted doubles of all characters, and there were going to be other versions of the same character I was going as in our group, too. It didn’t really matter, because the original members of the group had decided I would be the “lead” one. Well, in the past couple of months, this other girl has joined and has assumed that now she’s going to be the “lead” version of this character, without really asking or clarifying or anything. The other group members won’t say, ‘hey, you know, that was supposed to be what kell was doing.’ I don’t care that she’s going as the same character – it’s that she’s basically trying to take over my role and nobody is speaking up about it.
I don’t particularly mind if they want her to do this (I’d be a little disappointed, sure), but I wish someone would make a decision. I don’t want to speak up and say, “Hey wasn’t I supposed to -” and seem all high and mighty or something…

Gee my life is so tough, if this is the biggest problem in my life right now. LOL.
