He nearly got her in trouble with the law at that "post office" in the beginning.
Hi, in this film, with his acts of voyeurism and stalking, in order to get her attention, he inserted fake notes into her post box that showed huge sums of money, and as a result, he even got her in trouble at that post office, as that angry and blunt female postal worker started to angrily suspect her of forgery.
Now, in your opinion, WHY did he do THAT?
Also, did those postal staff members really need to get this angry and suspicious at Magda's character and even IF there MAY have been forgery involved or not, why were they so mad and coming to the conclusion it was her who wrote it, maybe it WAS someone else who inserted those notes or maybe there was a simple MISTAKE like that?
And when towards the end that guy Tomek, spoilers, cut his wrists, and probably died, did the postal staff workers sort of realized what was going on?
But seriously, what did we all think of the above err scenario, thanks.
