I saw a post on Facebook recently. It said if you can choose to be anything, be kind. Of course like all trite sayings, this is not quite as easy as it sounds. I know some people have mental illnesses that mean their behaviour is not always their own. They cannot always express their moods as they want to and their interactions with others suffer. Another group of people have experienced many tragedies in their life and are understandably grumpy and gloomy. Some people are not morning people, and cannot face the day until they have had their morning shower, or their first or second cup of coffee, or until the sun well leaves the horizon. Teenagers often go through stages when they are in bad moods for extended periods of time.
