As the old saying goes, "never judge a book by its cover." It's a whopping good piece of advice, too, as things are not always what they seem. That's certainly the case with this elderly couple. While their fellow restaurant patrons had their hearts in the right place, it turns out they don't have any reason to be worried. This husband and wife might be getting on in years, but they don't have any issues figuring out how to get through life's little obstacles ... And, even better, they seem to have quite a good sense of humor about it all. Those with ample food surrounding them (and everyone else) can certainly learn a thing or two from these wise diners.
