Uncovered windows- the neighbor's problem or the resident's?

I had a hard time thinking of the actual q for this, so sorry if it’s kinda awkward. :) And I am bad at making the details section short.

So let’s say someone lives in the city and their bathroom window faces another building.

For one reason or another, the bathroom window doesn’t have coverings. The woman who uses the bathroom doesn’t stand nekkid in from of the window flashing her bits purposely, but in day to day life someone looking through the window from the next building could reasonably have seen a boob when the woman hops in the shower or the resident popping a zit or just doing other bathroom type things (not toilet stuff though).

My question- is it primarily the responsibility of the neighbors to not look in the window if they don’t want to see the woman, or is it primarily the responsibility of the woman to cover the window so that the neighbors don’t have to see her, assuming the woman just doesn’t care a whole lot either way?

This is kinda a silly question, and just something I was talking about with a friend and have been thinking a bit about.
