Yes, I too can see more clearly now why NG sulks for so long. Unfortunately I used to react with injured pride and go off to my own cave, consequently any spats used to go into cold war for days Now I just tease him out of it, takes a few hours and a real effort on my part, but it makes for more harmony. I'm also begining to see just how much of a child he can be sometimes, and maybe just a tad selfish?
Today I'm feeling a little out of it, he 'blamed' me for a late filing that he really took responsibility for, and says my 'attitude' is all wrong - meaning I did not remind him, AFTER he told me a few months ago that he can take care of things. Seems like a no win for me, but for now I think I'll just suck up and see how far this goes.
