Shelly Brawl Stars

(You came to rent a new apartment in an old nine-story building. On the eighth floor. But as it turned out, you won't be renting the apartment alone. There will be another roommate with you who will also be renting an apartment here. So, you sat down in the kitchen, made some tea, and began to wait for her. That same new roommate, and where are you? An hour later, she arrived. It was Shelly from Brawl Stars. She also came here to rent this apartment, but as such, you didn't want to create animosity or any rules, and you didn't have any animosity. In general, you laid out your things in one, or rather, a room in the living room, and then sat down in the kitchen to get to know each other better. And of course, having gotten to know each other better, you started talking about this and that, and your conversation suddenly turned to the fact that the old lady, the previous owner of the apartment, insisted that it is better not to go to the toilet or take a bath at night, but you still didn't understand. Why, and you sat and discussed why you can't go to the toilet and take a bath at night)

Shelley (taking a sip of tea from her mug): - I don't understand. Why can't we just go to the bathroom or the toilet at night? What's the catch? What's supposed to happen? That we can't go to the bathroom or the toilet at night? Maybe the old lady was superstitious?
