It is my house but she's the one who cares whether or not we have a dryer. I'm perfectly happy to line dry myself. On the plus side, she has offered to pay half so she can be generous.

We actually get along better than I'd thought we would. She's extroverted and I'm introverted so I thought she'd be in my space all the time but she's shown herself to be considerate about my personal space. She's sort of Felix Unger-like and can get anxious if things are out of sorts.

I'm not going to bring it up over the holidays because they provide their own stressors, but I'm sure I'll have another opportunity to confront her.
