We must surround ourselves with happy people we are told. I’m not too sure I can buy into that concept as I feel we can imprison ourselves and others if we believe this. I’d say we should instead surround ourselves with people who care and that takes on so many different forms. People who care don't have to be 'happy' to add value to our lives, their caring is their loving no matter what emotional state they're in. We have to be careful about the concepts we accept.
