So today's Father's Day, MIL drops off SD and doesnt acknowledge DD at all. So I confront her outside and she says that I didn't stop in the house with DD the last time we were there, I walked through to the back and a few minutes later she went out mind you it was 90 degrees in the house and was cooler outside. That was her excuse. Pretty petty. I also told her it is not my responsibility to include her in everything I do. She just drove away without saying much. Needless to say MIL is not invited to DD party next month. She barely knows DD and she's 2.
