There was a story told by his former schoolmates that as military governor, he was being introduced to top civil servants. Then, he saw one of his seniors at the MBHS, broke protocol and greeted him respectfully pointing out that the civil servant was his senior, so how could he keep him standing on the line.
When he turned 70 in 2006, Johnson told all those who may want to give him gifts to monetise them and pay the money into the coffers of the MBHS Old Boys’ National Association for the completion of projects in the school, especially the Centenary Hall. That was a school he left 49 years before! But that was his character: he never forgot his origins, friends, relatives and colleagues.
