She needs to pee

I could tell she was thinking about the options I presented to her. She was thinking for a while when I saw her start to squirm. I was hoping it would be from horniness, but no, it wasn't.

"I'm sorry" she said "I need the ladies room. Do you know where it is?"

I tried not to look too confused in response "I don't know what you are talking about. Why would you need a women's only room?" I could tell she was feeling awkward. I wondered if this ladies room is some detail of how her old world worked. I asked more calmly "What do you need it for anyway?"

She was clearly looking a bit awkward, which makes sense "I need to pee". She explained quietly.

I paused for a moment, I still couldn't quite see the logic of how her old world worked. Thinking about it, it would have made sense for people in her universe to try and hide their genitals, while peeing, which I must admit, I hadn't really thought much of how that'd work. I was slightly curious to find out, but first I needed to explain to her "Well, I don't really understand how things worked in your old reality, but here, there aren't really any ladies only rooms for you to pee in. In any case, forcing half the population to lose access to you will probably come across as selfish."

I could see her obviously blink in surprise, then sigh in resignation. She seemed to realise she'd assumed another aspect of her old reality would apply here without basis. "I see" she said "So where should I pee?"
