Maude, a 79-year-old widow, met Harold, a much younger divorcee, at her town's Heritage Days' social. At first, Maude thought that Harold would be a great date to enjoy a dinner and a movie with, but soon after their first "date," Harold began critiquing Maude's cooking and cleaning efforts, and was forever looking at the world [almost any subject] with "half-empty" glasses. In less than a month, Maude decided that she did not want to be around such negative energy, so she dumped Harold.
