110 Intruder alert and melt-down

Last Friday night I took a shower at my parents' because I had put fresh sealant in my ever-leaking tub. I left my towel, soap, shampoo, body scrub, and loofah gloves on the sink in their bathroom and went into the dining room to work on the puzzle (still Noah's Ark). It was really windy and the wind was scaring the dog who kept barking. The dog went running into the bathroom barking and then my dad went in there. He came out whispering and hunched over, saying that someone was out there. My mother went into the bathroom and looked out the window. No one. In a normal tone of voice, she told him no one was there. He got very angry, slamming his hand like a karate chop into the table, whispering "yes there is I'll prove it". He then went into the bathroom and came out with my wet towel as "proof" someone was in the house.
(I can't make this stuff up, you know.)
My mom said that it was my towel. She pointed at me, sitting there with wet hair, as proof. He couldn't understand. She took the towel and put it back into the bathroom. A little while later he went into the bathroom and came out with something else of mine, saying "who's here? whose stuff is this?" We could NOT get it through his head that it was MY stuff and there was no intruder. It wasn't like I was hiding or anything, I was sitting right across the table from him.
The dog was really scared of the wind and he kept barking and barking and my dad started hitting the dog with his hat (not hard, more like swatting) so I had to rescue Ace and hold him, because if I put him on the chair he'd jump off and we don't like him to jump onto the hard floor (he has a bad leg). Have you ever tried to do a puzzle while holding a 16 pound dog?
This morning my mom called and said my dad had a melt-down in Target. She doesn't really know what happened. She thinks maybe he thought they were going to Yale (same highway, same direction). He didn't want to go inside the building, then once inside he got very agitated and loud, started yelling, people were looking and pointing, and she had to bring him home since it's too cold to sit in the car. She thinks he's upset enough to take off, so she doesn't want to leave him home alone. Thus I am drafted to Dad-sit tonight.
