I was at Wal-Mart and I saw a very heavy woman in the medicine isle in a motorized shopping cart with a small child around seven or eight walking with her. I thought that the woman had disabilities because she kept telling the little kid to get things for her over and over again, but to my surprise she just stood up and got out of her cart to go get something from the top of the shelf! Then after she got what she needed she returned to her cart and continued shopping with the little kid.
