You dealt him a low blow from what I can see and thats probably why he's pissed off. If you wanted a head you should of done the same as him and advertised for one, instead of jumping on his post. It makes you look like a proper vulture.

He certainly dont owe you an apology, if at all it should be you thats doing it!

Take this how you will, but it aint effecting my day in any way....
