I have a sister who I am very close to. We are very different but generally get on well enough. She is a terrible timekeeper, always has been. I have mentioned to her on numerous occasions that I find poor timekeeping really rude, she tends to shrug it off and say its my problem.
Last weekend I asked if she wanted to come to brunch with me and mam. I said I needed to be home at 2.45pm so suggested we meet at 11.30am to give us a couple of hours to browse the shops and eat. She said she was dropping her DD to dance at 12.10 and would be over then. Its about 15-20 drive from the class so I was expecting her about 12.30.
Mam and I browsed the shops from 11.30 - 12.30 and I rang sister at 12.30 to say we were going in to the restaurant so to come straight in when she arrived. No answer on the phone. She rang me back at 12.45 to say there was a change of plan with her that morning and she was only leaving her house now to come over and told us to eat without her. She arrived at 1.20 just as we were finishing lunch.
As usual there was no apology only excuses. I said I didn't want to argue with her but in future would she please send a text when she is going to be late. I said she knew long before she phoned that she wouldn't be here on time and could have let us know then as we were waiting until 12.30 for her before eating.
She said no, she wouldn't send a text as there was no need, she was only 45 mins later, she didn't expect us to wait on her, we could just have gotten on with our day and didn't need her. She totally gaslit me over it.
A few months ago we arranged to meet up with our children and SIL and DN at 3pm to shop and get hot chocolate with the children (the place we were at closed at 5pm). I rang her at 3.45pm and she was in a different town. She said "oh just carry on, you don't need me there..". She arrived at 4.45pm, no apology and carried on like nothing had happened.
Anyway it seems now she isn't speaking to me after last weekend.
I do think she has ADHD, she is very disorganised. I try to give some leeway. I have a friend who is usually late but its always only 15 mins and she almost always texts and certainly always apologises so I don't mind.
AIBU or is she in the wrong?
