When you are looking for a Bro, and only a Bro, you should probably uncheck Dirk’s box on Parp, and if you leave it checked, you should not be surprised when the Dirk you get acts like Dirk and not like Bro. Just because some people use Dirk’s color for Bro does not mean they are the same character. Just because someone is on Parp as Dirk does not mean they are in the mood currently, or even ever, to play Bro because you try to pressure them into it.
I really thought this problem would stop when the guardian checkboxes got added fucking forever ago. It has not. I still routinely run into Daves and Johns, while playing Dirk, that are shocked and disconnect from me when I act like Dirk instead of Bro.
(for fuck’s sake, guys, use the fucking checkboxes when you don’t want a character. That’s what they are there for. Nobody will ever know.)
