I am not first timer stay in high-rise. At least 2 uni hostel, 4 appartment / condo i stay before this, but this is the first unit I owned, maybe my renovation offended them. But I been accepting their *dinosaur walk* , *dragging chair*, *hulk run* and *steel ball dropping* for 2 years, enough is enough!

Polite talk is not permanent if the person have bad nature, they might silent for a period but end up they will forgotten one day. Also you are deal with 1 family and not all family members will care your complaint.
