I think its because he called me an imbecile. Personally, I wasnt offended, as I am indeed an imbecile.
I've been called worse.....and I've dished out worse. I'm building up a list of stuff I'm not allowed to say because I don't want to be banned.
I prefer to be called a moron, though. Imbecile is only an IQ 26-50 but a moron reaches the dizzying heights of IQ 51-70. I knew that half term of psychology in 1989 would prove useful one day.
