Help! Our handyman has gone postal

We are facing a strange challenge at Casa Journaliste. Our handyman has gone nuts.

While we're both fairly handy people, our eagerness to take on big projects is hampered by the obvious softness of our keypad-trained hands. So we have The Guy who comes in to do the big lifting, leaving us the wussy jobs like sanding and painting. But lately, we've been having a few issues with The Guy. Relatively minor things, so we were willing to look beyond them.

This morning, though, a pool of brownish water was plopping onto the kitchen floor. Looking up, drops were forming in the door frame. The kitchen wall was clear, so I walked into the dining room, and found a wall clogged with water bubbles. Downstairs was even worse. Turns out that when The Guy was putting up crown molding, he nailed right into the plumbing we had done two years ago. Sigh.

Quick call to The Guy, and he's over here ripping out the crown molding, cutting open the wall, and then dashing out to fetch a stopgap fix. Quick call to our plumber, and he's warning us to not settle with a stopgap, and will be over later today to repair it properly.

We're staying pretty quiet while all this is going on, but our displeasure was quite evident. The Guy then drops a rant about doing work for our extended family, and how one member has been badmouthing him and he's never going to work for this family again. Hmmm. We back away slowly making placating sounds.

When The Guy tells us he'll come back to finish the plaster Friday, and will sand Saturday, I tell him it's a no-go. We're having a pre-Christmas party that day. Fair enough, yeah? He looks at me in incomprehension, then starts staring off into the distance, his head nodding as he tries to figure all this out. Husband asks if the job could perhaps be started today. The Guy says the ceiling plaster is still wet. The Husband says "Oh, okay, I didn't know how long it took to dry." And The Guy storms out! Just like that. SOOOO weird. 

The Guy is in the middle of some fairly hefty issues - marriage breakdown, big fight that ended with police charges, mandatory anger management course, etc - so we're more concerned for him than for the house (although the house damage is a major pain in the arse). But seriously, dude. Calm the f. down and just do your job properly. We're not asking for brain surgery here. Just smooth walls, and maybe a paintable ceiling before Christmas.

Are we asking too much? Are all handymen vaguely off-kilter like this, or are we just special?
