I just recently had an amusingly short encounter with an angry den claimer. I think I may have found their off switch or something.
DenClaimer *rage face*: hey, get out of here!
Me: Why?
DC: this is OUR den!!
Me: No, it's not.
He kinda stood there with the rage face for a few seconds and walked back to his RP, and I just sat there for a while. XD
There was also a time when I decided to join an Avengers RP on a whim (it was a really slow day) because the Loki spot was open and I thought he'd be fun to roleplay. He probably would have been, but the group, once arriving at the randomly designated RP spot in Ficho, immediately started speaking in such broken english I couldn't figure out what was going on for the life of me, so I just sort of stood there awkwardly trying to sort it out. I'm pretty sure they started shipping all the characters right after that, which was when I took my leave. Too bad, really, I could have had a lot of fun doing that...
