My neighbour told me yesterday that the lady above her wears shoes in her apartment and is constantly stomping around on the wood floor. My neighbour is very frustrated by all the racket. She said she had complained to the lady, but she had not changed her behaviour. I suggested that she buy this woman a pair of slippers as a polite nudge.
If you live in an apartment block, you really need to think about the people beneath you and stop wearing shoes inside.
