Last week, DH asked MIL if she could help out by coming to our house when the washing machine man was coming as I have an appointment. "yes yes, of course, I'd love to help."
Yesterday I rang her to check details, confirm arrangements and explain slight variables based on uncertainty of when he would arrive, "Of course, I will come any time. Just tell me. Wake me up and I'll come straight away if you need me early."
This morning, I rang her and asked if I could fetch her at 10:00 instead of 11 as was worried I'd be fetching her when the man arrived: Angry/defensive tone: "No, I have lots of work. I need to be at home as much as possible today. Come at 11 like you said."
Why? WHY?
