Things People Hang on Their Main Door

I know I just posted a super long posting already today but can't resist a little gossiping. I can't help noticing one door of one of the neighbour at the apartment that I am staying now. At a glance, we thought perhaps since she have two young kids, she is just teaching her kids but hanging up reminder at the door grill.
We didn't dare to stand at the door too long to take a better pic but even from this pic, can see alot of paper and stuff hanging on the grill. And on the door itself, alot of chinese amulet/charm (sp?). Anyway, since it was just the end of the ghost month/festival, this is hardly surprising right? But upon closer inspection, this is what we found written on the paper hanging on the grill:

It says:
Mind you own
business.
Jangan jaga
tepi kain orang.

And someone has added the word:
Why not?

It says:

Do you pay any of my bill?
No?
GO AWAY!!
Private property
Trespasser will be prosecuted!

Don't ask me why like that or if she is unstable. I think maybe but I dare not find our. Later she amok and run after me with a cleaver how?? :P
