My mother once threatened to evict me (was still living with them) because I asked her to back up her important files for me to carry them over to the new office computer I had set up for her.

She flat out refused to even attempt it or answer any of my investigative questions. This woman had been using windows computers for work for over 20 years at this point, but the thought of opening an explorer window apparently terrified her so much we got into an actual shouting match over it.
