I can only assume that she was a visitor to the town home complex, if she had lived here she would have presumably had an ample supply of diapers at home. I think that she may have been on her way to her car to possibly purchase some diapers when she heard my giggling boys and thought that since my kids were so little I was bound to have a bounty of diapers. She was lucky that I did not switch over completely to cloth diapers. Had that been the case I would have been a lot more reluctant to hand one over to a stranger. They are quite expensive to replace.
