I went out of town for a couple of days to stay with a friend. I got back today, picked up S from the sitter. The sitter said that W noticed I wasn't home when she picked up/dropped off, so she was asking about me, if I was ok, etc.

This morning, W sent me a very polite message asking me if I could pick up S. I was planning on it anyway, but getting a "Good morning. Would you please pick up S at 6 today?" message was kind of unexpected.

I politely thanked her for the reminder, said I would pick him up, and told her to have a good day.

Doing the GAL thing seems to at least be giving her time to stop being so angry. I like it.
