Is it okay for someone else to lean a mop against the wall in my living room?

There is no good or bad question, if the house can't withstand the reliance of a mop, then the house will not be able to live, but your unwarranted worries are not conducive to your normal life, and I am really helping you look forward to adoption,

Answer: What does it matter if someone else's mop leans against the wall of the living room, as long as it is not put in your house, it is someone else's way of life, and you have no right to interfere.

You're talking about the other wall in the living room, which doesn't belong in your living room. People can put it anywhere in their house.

If you live with someone else's family and you want to divide the area, then you should discuss it carefully.

Not good, the mop has water, easy to soak into the wall, causing damage to the surface of the wall, over time, it is easier to cause cracks in the whole wall, causing potential safety hazards.
