It's clearly a change, @Greek.

Since the end of June when WAW split, it's been "our house" and "Mom's new house." I know for a fact she didn't like that; in her words, "I wish the kids would act like my place is a home."

When I took them to school last Friday, they asked, "Are we going to Mommy's house or our house tonight?" I told them they were spending the weekend and some extra days at their mother's house, since she was going away for the holiday weekend.

When I saw them last night (I had to take The Boy to his football practice because WAW had a late work thing) it was: "Are we sleeping at our house tonight, or are we going to yours, Daddy?"

When I said, "My house? Isn't it our house?" they both looked at each other with that uh-oh-we'd-better-shut-up look that guilty kids have -- the one they don't think we recognize is that look.
