Upstairs, downstairs, adjacent, and diagonal, too?

Goes quiet for two weeks … Honey, I think we should go check on the neighbors upstairs, I’m worried about them

Neighbors upstairs: … aw no, don’t worry about us. The upstairs neighbors machine has been in the shop because it broke down a few days ago. We’ll have it on again tomorrow

So when bI move from morning shift to night shift are these standard issue or do I have to buy my own?

This is gold

Ok but what exactly is going on here?
