I needa find this idk why but it was about this single dad I’m pretty sure he had a son and I don’t remember much but it was in black and white he was like chubby and he was with this guy I don’t think they were dating but I remember this one scene they were doing “it” and the guy put a leash on the guy then the son woke up then guy with a leash hid in a near by closet or room and the kid asked where’s my dad and then the guy oh he went on a walk you should go back to sleep then I think that’s all I know
