I can understand how you guys feel! I guess it is unavoidable to have inconsiderate neighbours. Mine too!
There was once my above dunno which neighour pour some dirty water. My window was open & my parquet floor & bedsheet got wet & dirty. I got to wipe & wash my just changed sheet. Sigh....
My dunno which neighbour also throw those bulky stuffs outside the dustbin chute. But what to do! Neighbours mah! Got to face each other often. Just endure loh! Peace & harmony mah! My family always throw the rubbish properly down the chute irregardless of how big the rubbish are. Dun understand why they can't take all the trouble to do as what we do.
