Two examples.

The walker

I was taking the car with her grandma already inside. My partner was outside with grandma's walker, usually I take the car from the parking spot and then my partner will put the walker in the trunk because it's easier like that.

She closes the door after helping her grandma to sit on the passenger seat and says something about putting the walker inside afterwards.

She goes to the side of the car, and I turn on the car at the exact same moment when she suddenly goes to the trunk. I had the car in P and nothing could have happened, but I was surprised she wanted to put the walker inside the trunk while the car was still in the parking spot in our garage.

She starts angrily telling me that she burned her leg because of the exhaust of the car (my car doesn't even have an external exhaust, it's hidden underneath the car), I apologize and turn off the car.

She gets inside and argues with me for 10 minutes telling me that it was dangerous, that she felt the heat of the exhaust etc.

I try to explain my side of things and she becomes pissed because she wants me to just say "I'm sorry.", shut up and then claims I never take accountability for my actions.

The guests

We had some guests one night. She always keeps bags and other stuff near the coat rack. I had told her to remove that for several days but she never removed the bags and her 5 coats.

The guests were coming. I grab all the stuff rapidly and put them inside her office.

Some days later she was looking for a bag of hers. I couldn't find it at first and then found it where I put them in her office. I searched for 10 minutes or so.

She was pissed because I touched her things without telling her and while I tried to explain why I did it, she just demanded I apologize and shut up.

She claims that I always need 20 minutes to explain myself after I do something that pisses her off.

I'm just trying to explain my side of things. Because I want to make it clear that it was either a misunderstanding or not done in bad faith.

AITAH?
