Took the kids to see Harry Potter (good), dinner, then playground.
When picking up th kids, WAW was again very nice, exchanged some invoices, told her the tire looked low on the minivan and she said "thanks for seeing that."
She said if I was going to keep them longer tonight, to call her dad's cell phone...as a reminder, the in-laws have been living with her since Feb. I said, "is your phone broke." (because she just chaged carriers & phone.) W: "No, I'll be out."
Didn't come across boastful, just matter of fact.
When dropping them off, there was a high-end car in their driveway, which must have been one of her new "friends." Girls night out I suppose.
Nothing major, continued civil interaction in person. Which, as mentioned, is a major change this past month instead of the venom waw had over spring.
