Your Mom is lucky to have you and your Son to help her with her move. I could not handle the winters in Wisconsin but it sounds like this is where she is from so she should be ok with it. I was born and raised in Florida, I lived up north and did not like the winters.
Mom packed for Florida Summers, not Wisconsin ones. She already looks like an Eskimo.
The good thing is her apartment, food, and activities are all inside, so she should be okay IF she finally takes her sandals off and puts socks on, and stops telling me her feet are not cold while the rest of her is under blankets. :D
I feel for her, I went to New Hampshire a few years ago, it was in July and I froze my ass off. It is nice that everything is inside for her. Wishing her warm thoughts.
