She in the shower when she hears footsteps in her living room. She lives alone; it is unlikely she will be heard if she starts screaming. She is several stories up and the bathroom window is too small to squeeze through. When she peeps out her shower curtain, still hoping she is imagining it, she sees to her horror that the batheroom door isn't even closed, let alone locked.
She is the kind of woman who cares a lot about looking good.
So if she is going to try to fight off her attacker, what would you put in that bathroom?
[Full disclosure: this happened to me about 25 years ago when someone broke into my apartment.]
