Hmm. Don't take stuff like this too seriosuly, guys. I am afraid I cannot agree this is unacceptable behaviour seeing as it was just a joke and immediately declared as such. People rampantly took the piss out of myself and Edna all the time. That's one of the points of friends, isn't it? To laugh and joke around with that sort of thing?
Still, if Fire is going to be so very sensitive probably best not to do this again.
