Her dad gave me the creeps, it was just as well. My mother did say her mother tried to sell her some plastic items, maybe they had a spat during that discussion. My mother is pretty open minded, she knew about the easyboy, but she didn't know about the photos - so who knows. I should ask her about it. Her step-sibblings wanted nothing to do with him either.
Sounds like your mom is a smart lady.
One of the big concerns is that leaving sex paraphenalia out and about for children to find is indicative of an attempt to normalize it. It's a big red flag for future abuse. What's the matter with modeling those things for your friend's dad hey? They're sitting out for everyone to see, surely there mustn't be anything shameful about them?
