I might be the only one who didn't know this but...
When I went grocery shopping with my niece two summers ago in Texas, I grabbed a cart and stuck my purse in the top part of the cart. She stared at me for the longest time before she told me that people put kids with dirty diapers up there. I couldn't believe I hadn't ever even thought about that. And all that time I was putting my nice purses there. And I would save the top part for my bagged fruit and veggies. Oh my!!! Makes me cringe when I think about it. Did you all know that? I can't believe I never thought about it before.
