I Am Annoyed By My Roommate

For some reason every night before my roommate goes out she asks me "What should I do if I get robbed" and I say run then she ask what if they catch up and I say if you stay on the main street that shouldn't be a problem. Then she asked me "what if I want to walk down a dark alley?"

And I am too the point where I don't understand if she is seriously, sincerely is asking these questions or if she is just trying to joke because she asks me EVERYTIME and I answer the same way, stay on the main street where everyone is driving😑
get a tazer, I don't know. Im running out of advice...
