Well they came and picked up the furniture and one of the Kayaks. I was gone but D18 was home. I noticed that D14's bedroom door was open. Her bedroom (when she visits) is upstairs, so I asked D18 if D14 came with them.
She said no, why, then said "Oh, I left the door to her room open". She then went on to explain that her mom called her on her cell and wanted her to come outside to talk while she was here. D18 said she didn't want to (because OM was here) and so she decided that her room (which is downstairs and has windows that face the front yard) was too exposed and she didn't want her mom to see her and maybe knock on the window.
So she went to D14's room and read her book until they left.
She's really having a hard time this holiday season. Last year was pretty bad, but at least then OM wasn't thrust in her face as much.
