I, too, am sorry this happened to her. Our newspaper carries the Mary Worth comic.......and she had her wallet stolen. She'd hung her purse on the back of her chair while having lunch. Someone apparently walked by, reached in and stole her wallet. I have to admit, I've done the same with my purse!!!! Also, my bow tuck bag doesn't have a zipper --- the next one I make will have a zipper ---- it just makes it a little harder for them to steal.
Oh -- and one time I was in line at a grocery store in a large city. I saw a man reach up to a young girl's backpack and very carefully unziped it, and took her wallet. I yelled....he dropped it and took off. So watch the backpacks, too!
