Thanks, everyone. I am not going to hold T's ant killing against him. He was in kind of an awkward situation, a formal legal meeting, and he had brought a slew of ants onto the table with his flowers. I think he was trying to clean up his "mess." It was still kind of disturbing, but I'm OK.
It brought up some other stuff for me, like how two days before the legal meeting, I went to see my psychiatric nurse practitioner, and there was a large fly buzzing around the room and it was quite distracting and annoying. She opened up her window but it wouldn't fly out. So we just lived with it. That was OK with me, as I have memories of when my husband was still living with me, he would get very annoyed at flies in our house, and take a rolled up newspaper and stalk them through the house. Then "whap" he would go loudly with the newspaper, striking them from where they clung to the wall, and they would fall to the floor, dead. There was some triumph in the hunt. It was violent. So I liked that my PNP just let the fly buzz around and didn't make a big deal about conquering it and killing it.
Then 2 days later comes the legal meeting and my T was killing ants. I think it reminded me of my H and freaked me out a bit. I don't like my T to remind me in any way of my H.

Because he's not like him at all.
