I had trouble with the 7-year-old boy being diagnosed as a hoarder. How many of you have had kids this age - isn't it pretty common for kids to not want to give up toys? It takes strong parenting to get a kid to cooperate with downsizing their toys, like telling them they can trade in 20 stuffed animals for 1 new toy. It's very clear that this kid, being raised by a hoarder as well, didn't have anyone telling him this was a problem until these psychologists get involved.
The mom herself didn't seem like a hoarder so much as extremely lazy. Yes, she shopped for stuff she already had, but when she had a duplicate she would have done something with it except she was too lazy to get to the post office. That is not the same as previous hoarders we have seen who invest a ton of emotional energy into mundane objects.
They needed to declutter and clean. They didn't fall in love with their trash like some of the previous shows, like the young man who couldn't get rid of dog hair because he thought it would kill his dog.
About the junkyard guy, here's an article on the local news about him.
