Mike, you have my complete sympathy and understanding. I never understood why people with children seem to feel an unavoidable need to pity individuals that make a choice to not have kids. Its arrogant and the whole "we know better" attitude make me want to puke. Not least when it comes from parents that arguably should have limit their "parenthood" to the cat.
That said, I have kids up to my neck both at work and at home and I mostly enjoy it. Yes, I said mostly..
