Three Creepy Stories, Part 1: The Guy and His Grandma

I spent my childhood in a shithole Siberian town, the years weren't the most ancient, but not exactly recent either, right when the craze for creepypastas, Jeff the Killer, SCP and other porn-anal activities kicked off. Not everyone had internet back then, and smartphones were only for the rich kids, luckily I was one of them, and on my initiative we and the other little shits started telling each other stories, partly made up on the spot. There were plenty of coolstories about "the sinister basement with the plumber's ghost", "the ghost of a little girl" and other bullshit, but I'll retell the coolstories that seem closer to reality to me, or that I saw myself, and + at the end I'll tell mine. The stories will go in order of escalation, from the more realistic to the more paranormal.

Story one, the everyday one:
There was this one dude, he lived with his grandma, communicated by mooing and relatively random words, and he also stank of some kind of borscht, fuck. He lived with his grandma, she constantly gave him sweets, but couldn't really look after him, either because of sclerosis or because of her own head problems. In the end the dude walked around with black teeth from cavities and, a couple of people saw it, he was actively being fed urine so he'd "grow up healthy". And anyway this little chelibasik suddenly fell in love with a girl from the yard and tried to hit on her, it went so-so, but sometimes he'd come out with something interesting for us, which she gladly retold to us. According to her, he said that when he was little they lived with his parents somewhere in a village in the region, and they started bringing in more and more kinds of guests, their description ended with them being bald, and even the women. Then he got his head shaved too, and his parents shaved their heads too, they brewed tea with salt, uttered some strange abbreviations and stared at the sun for hours, "charging up" - as he himself put it. This kid, by the way, did that too, we thought his little brain was switching off, but turns out he was standing up to photosynthesize for real. And then his parents, according to him, went off somewhere, and that was it, he never saw them again. In the end on the third day the food in the fridge ran out, and he went out into the streets to look for some, tried to swipe bread from a "bearded dude", the guy beat him like in that video with the homeless guy and the compote, and that's how the district cop found him, sending him off to his grandma. And then the spirits of his parents cruised over the yard, the local locksmith opened heavy fire on them with a nail gun and the yard exploded. But seriously, that little shit disappeared at some point, I assume the grandma just died and he was taken to an orphanage, no idea what's with him now, but with a background like that you can't expect anything good from life.
