I believe my friend is being abused by his foster parents. Im not positive but yet, I was in the room when their foster dad started physically abusing him. When my friend started to stand up for their self, their foster parent asked if they really wanted (his foster dad) to beat him up right there in front of me. I snuck into their house so, they threatened to call the cops. But I didn’t do anything wrong. So they let me go, but I havent heard from my friend since then. I don’t know what I should do?
