Hilarious!
(I'd like to have one of those leaf blowers to take to the supermarket, to blast away the oblivious loons, that insist on stopping their grocery cart in the middle of the aisle, so others cannot pass!

So happy your parents have moved back into their house. I'm sure that all the moving "helpers" are probably sore after a few days of lifting and moving boxes and furniture. (Moving is a bear -- been there many times in my life.)
Bummer about one of the companies you all had to deal with, during the rebuild. Sounds awful. And I agree that even though you can see certain things not properly done in the house, best to keep it on the low down with (some) other family members -- and deal with the issues separately. As you said, your parents have been stressed out over all the upheaval in their lives this past year, so no need to add additional angst at this point. They seem happy just to be back in their own home, and that's good enough for now.
