My sister-in-law was a renting house a couple years ago. She lived 200 miles away, called and asked if I would go over there and fix the AC, and check a gas leak on the stove.
OK, so I get there, there is the tenant, running around in the side yard, and I mean running, like running in circles, pretending he's an airplane or something! I knock on the door, kid lets me in, place is filthy. I get started on the AC, which the evap is totally clogged with pet hair and years of neglect, not a quick fix.
In comes the tenant, starts in on me about what a horrible place this is to live and he's not paying his rent until everything is fixed. If I don't do something he's calling the sheriff... This guy is freaking out! Wierded out on meth!
I'm explaining I'm just there to do repairs, I don't own the place.
"Well you're lying! Yes you do own it!"
This was getting scarey, but he finally goes back outside, I get the AC cleaned up, and start on the gas leak. The complaint was the gas valve won't shut off, he can smell gas when the line is disconnected. I wanted to ask why was he disconnecting the stove, but knew better than to try any communication with him...
So I turn off the gas, take the valve off, take the twisted and ruined flex line off, go into town to get parts. I get back and the gas company is there. He had called them and reported a gas leak!
I go in, the man from the gas co. goes in with me, we replace the valve. He's looking around the house, the tenant keeps coming in and going out, spouting off crude insults, tells his kids to watch us so we don't steal their stuff... Gas man is figuring out who's who, asks what's going on, what's wrong with that guy?
"Meth" I answered.
"Whoa... I think you got this, just turn it on when your done. I'm outt'a here!"
That was a freaky situation, not something I ever want to put myself back into! Looking around the kitchen, there was profanity, nonsense poetry, Satanic symbols written in marker on all the walls! What was sad was the kids, little kids growing up in that! None of them ever spoke a word, just stood wide-eyed and started, watching to be sure I didn't steal anything, as if there was anything there to steal.
A couple weeks later, SIL calls me, wanted me to go tell them they had to leave or pay the rent... I declined the offer!
