Cougars are pretty evil. I mean, I look at my son's friends and granted like some of them were a bit, waify and whatnot, but most of all 21 year olds look like they would SNAP like a twig if I climbed in bed with them. They would have to learn a thing or two about leverage.
And an old lady making your son work OVERTIME? Bah, I'm surprised she gets to visit at all.
Perhaps she is in possession of the "magic vagina" as my kid once said sadly about a girl he loved, but couldn't be with, because she was a MASSIVE alcoholic and he got to see how that went with his dad. Poor little guy. He used to talk about her wistfully and I'd be like "Maybe you can be her friend and help her?" and he was like, "Nah, Mom the only way you can be with someone like that is to drink with them."
And I was like, "You are wise grasshopper. When I accidentally got pregnant with you and had to pay attention to how my life sucked? Big time? Yeah, that was the beginning of the end.
All the best to your kiddo.
