Options:
1) Move out - Very high chances you may end up with an even
worse upstair neighbour with more kids, or worst ! operating a
small factory above. Then waste all $$$ and effort.
2) Play loud music - Your upstair neighbour won't hear but your
side neighbour would surely hear. You become a nuisance to somebody
else
3) Complain to police or town council - chances are they will
play tai chi, and move you from one department to another. What is
the likeliness they can take action? Arrest your upstair neighbour?
Any proof? Very hard to proof
4) Use pneumatic drill to disturb upstair neighbour - again you
make new enemies with your side neighbour, may disturb the baby,
etc. Moreover, more holes in your walls.
5) Use bamboo pole - So far best idea. Very conspicious, upstair
neighbour won't know you do it intentionally.
6) Buy house - cannot afford
7) Move to highest floor (no upstair neighbour) - Good idea
!
8) Buy house in Johor and go to work via causeway - Good idea
but get stuck in traffic, got to wake up earlier
9) Kill the upstair neighbour and dump their bodies in Bedok
reservoir - Hmm, tempting but very hard to smuggle out bodies for
disposal.
So option 5, 7 and 8 unless there are better suggestions.
Better put a bad spelll/cure on your nosy neighbour, like
buy a cross or chinese octagon mirror, make them go mad
