PSA: Having or being a guest in an apartment. Show more
Apartments are attached to places where other people live. They share physical boundaries, plumbing, ventilation, and a great deal of other things.
Striking a countertop by way of mortar and pestle, chopping, or otherwise causing something to come in contact with a surface, transmits that force into the ceiling below *very* efficiently.
Heavy steps, dragging a chair or table, or anything else has the same effect.
