Was called last night by SIL who asked me to look after her DD tomorrow so she could attend an exercise class. I asked what time from and to, as we have plans for today. She would drop off DD at 7.45am and wanted me to have her until 2pm. Unfortunately we are expected for lunch at a friends at 1pm so I said we could have her DD until 12.30, this was not good enough and she told me to shove it and hung up.
10 minutes go by and we receive a call from MIL to tell me how incredibly selfish I have been and she rues the day I joined her family.
So, was IBU to say I could only look after DN until 12.30 or should I have changed my plans?
