Without a sense of humor I don’t think I would have lived as long as I have. When as many things fall apart as have around here recently laughing is the only option. It really reaches the ridiculous. Today the water went nuts and decided to gasp out of the faucets and produce brown water. Fortunately I have a husband who can see beyond the ridiculous and solve problems. So we are temporarily able to shower and have water to drink. Further solutions will come in time.
I think if asked what is the most important trait needed for survival and sanity I would have to say sense of humor.
