Yeah, it's pretty lame that some people acted like that in groups and with cosplaying. That's the negative impression I usually get from Turk cosplay groups, they all have been pretty domineering and rude (not every person in the groups, of course, I'm not singling people out, I just mean the groups as a conglomerate presence).
But anyway, good luck with your Cait Sith cosplay! If you need any help with props or something, just let me know.
We can get photos of Barret and Cait Sith fighting Bahamut-Shin, lol.
