Don't be a shit parent and no one will come looking

So for an HOUR I thought what I was hearing was a old cat or something growning outside. I live in an apartment and all noise echos so you can't even tell what walking is sometimes. I go to take out the trash and as I'm walking past the stairs that go to the next floor I realise the sound is a kid crying this low, miserable, depressed sounding moan. Not a tantrum cry or a I'm-scared cry but a I'm hurting cry and again I know it's been an hour because I took the trash out when my show went off. I try to keep walking, but cant. I put my bag down and walked up thr stairs. There's a door open and I know who's in there. It's someone I know to cusses at her kid constantly while he tries to act tough. The type of woman who probably did drugs at some point and would slash your tires. God help me, I knocked on the door and peeked around it to see a livingroom. After hearing mom ask "who tf it is" and telling her kid to ignore me I wait. He's still crying. He eventually came to the door wiping tears off his little face and acting tough again. I ask him nicely if he's ok. He smiles at me and says yes. I hear mom in the back saying "what the fuck really?". Uh yeah, really, who lets their kid groan at the door for an hour? I tell him I'm just checking and when I turn around mom obviously slams the door. I think I already told that story here but I saw that kid again. She still cussing at him and has weird behavior. I swear she's fucking the local drug lords with the bits of conversation I overhear from the echoing hallway. I can't prove anything obviously. I feel bad for the kid. Why the fuck even have a kid when you don't want it? Don't pretend it's because you're Catholic yet happily do all this other shit. At least your kid is relatively safe here.
