Pete, in an attempt to diffuse this situation, he's definitely calling you a liar, in plain daylight, and needs to be dealt with through an mean and uncompromising form of punishment.
Just my 2 cents, to try to calm you all down a bit and put this in perspective.
ps. fightfightfight!!
Well thanks for calming things down mate, it is greatly appreciated, I just didn't want to get carried away with the idea he was 'aving a pop.
I will however wait for his response before I get nasty...just to give him the benefit of the doubt ya know, I mean, he could just be stupid which would go some way (but not all) to mitigating his accusations.
In the meantime, I think I'll continue practicing my kidney shots...
