How can one be critical of common sense, and how can it be a waste of time, to encourage it in our youngsters, I have seen very little of it recently as it has become a rare commodity, if it has to be re-taught, so be it. Cheap at half the price
As for BEING happy that is illusive a bit like good weather at Wimbledon in the UK, I will settle for being not UNhappy. Although it should be the birthright of EVERY CHILD to be happy. (and maybe that would naturally lead to the adults also becoming more positive, lots of thought provoking stuff there!)
