Pro's bitching is like clockwork -- over the years we've been doing this writing thing I've pretty much come to expect it... [...rassamnfrackin...]

Difference with Pro, though, is that his bitching is usually constructive criticism rather than just outright criticism. I know I'm a lot more willing to listen to someone who can see the strengths in my writing and point them out along with the weaknesses than someone who just points out my faults.
