I’m trying to imagine what it would be like to be living with uncertain legality in an apartment in another country, where I don’t speak the language, and I’m not sure about the integrity of the police, and I hear a child being abused.
I’m not the kind of guy who can confront anybody physically, but I can often get my way, despite that. In one case, to protect my brother from abuse, I negotiated a buy-out with the guy who was giving him a hard time. Better lose a bit of money than my brother.
Another time, the neighbors all got together to confront one of us who was disturbing us in a variety of ways. It was tough to get them organized. No one wanted to do it, but after a while, they realized they had to.
I had a roommate once who was making life miserable for the rest of us. One of the roommate’s boyfriends was a tough guy, and we got together, and told the jerk to move out if he knew what was good for him. He did.
You have limited options there. I was thinking you could mug the guy one night when he’s outside, preferably coming back from the pub. Maybe break an leg, so it’s hard for him to chase the kid around.
I thought you could talk to the neighbors, and see how they feel about it. If there is anger, you could try to organize them. You could also have the gf talk to any Polish agency that might be involved with kids to see what they can do. There may also be some private agencies that could advise you in a situation like this.
You could also complain about the noise, and tell the guy you’ll burn down his apartment if you hear noise again. Remind him that you live right below him. You’d have to do a crazy act to carry this one off. But everyone knows Ozzies are crazy, right?
Ethically, I think you have to try something. It’ll weigh on your mind for a while, maybe even a long time, if you leave Poland without having tried.
Anyway, good luck with that. You’re gonna need it.
