My mum's upstair neighbours have got themselves a thunderous treadmill and everytime they it use her ceiling and light fittings shake violently.
They are a young couple and are really ignorant so she doesn't want to say anything to her. The girl is a right little princess and really rude. The late night parties she can accept (after all she does live in a flat) but she is really concerned about the structural integrity of the 1950s built ceiling and doesn't know what to do given their attitude and previous responses.
Despite polite requests they didn't cut the communal drying green for the three years they have been living there until she started to only cut half of it and they have flooded her several times. They had the audacity to say that "it was only a bit of water" and that she was nothing but a moaner.
Luckily my brother is not around at the moment. He is a erm...colorful character and i dread to think what action he might take on his return. So any advice (other than "move her") would be much appreciated.
