Weekend Getaway Turns Into Child Abuse Nightmare

Graham invited me to this like weekend getaway for DND and I accepted, thinking it would be cool. It was at one of his old coworkers house like "upstate" in a rural area. There was construction going on at this house as well and we had to help out with a lot of it. We were going to play a big weird dnd type game campaign at night. Didnt really sign up for a weekend of manual labor and the bathroom to our floor was broken so we pretty much had to piss in a bucket but I was still open to the weekend. After moving a bunch of heavy bags or garbage and wheelbarrowing a bunch of shit, we were finally going to get to the games. The house host and his friend were pretty much Adam Stio and Vince omondsen(but not the same IRL, just same bodies) and Adam had a kid with the woman who was leading the construction charge all day and they also had a baby who was like 1-2 and an absolute terror. As the day went on I realized why this kid, both kids, were so misbehaved. They were totally abused and neglected by their parents. At first I hated this baby cause he was violent and loud and couldn't really get away from him, but then I realized it was his parents more than him. More than once I asked myself how Graham couldn't see thru this and that these people were pieces of shit and he could find other dnd friends. I was given a role of moving all the trash inside to the curb to make room for this game were we're going to play and the little baby followed me outside and was like running around in the street yelling. Luckily there was no traffic or houses nearby, and thats probably how they got away with their parenting so far. The baby came up to me and scratched my legs or something so I had enough and picked him up and pinned him down to the top of the garbage bin. An ugly little creature. He squirmed but I held tough and asked what his problem was. He, in baby, made out that he wishes he was a "fetnyl baby still" and that made sense to me that his parents just fed him tranquilizers to shut him up and when he was off them he was crazy. This made me so sad for this kid, he was only like 2 and already his life was off to such a hard and bad start. I almost cried right there and the baby saw that and became somber and still as well, feeling that someone actually felt something other than hate towards him. I rubbed his belly now and said he had a hard road ahead but he was strong and would find his own way and get out of here. While absolutely thinking the whole time that I'm going to call CPS cause these people sucked. They also told me about the older boy, who was much quieter and I didn't know why, and somehow saw a flashback or home video of the parents like hitting his head into walls and hitting him with things so the kid now definitely had brain damage. So I was definitely going to call CPS and definitely not staying the weekend. I think they said they were going to take acid or shrooms to play this game and there was no way in hell I was gonna get caught on drugs in this nightmare place. So I was planning on how to leave, it was like 2-3 hours from nearest city, and was wondering if I was gonna tell/bring Graham or not, cause he seeemed all in on just playing this dnd campaign game. Woke up
