The pleasure was the more intense when one of those appreciative pupils was dyslexic. Through my own family I had such wide-ranging experience of the multitude of problems associated with the condition that I knew I could offer special encouragement. In an uncomprehending educational system, whether state or private, the dyslexics in a class, like my own sons, would typically be told that they were slow, stupid or lazy and would be sent to sit at the back of the class. Dyslexics are not stupid. Generally their intelligence quotient is higher than the rest of the population but their overdeveloped brain has squeezed out some other facility, usually associated with language or short-term memory. An intelligent child whose powers of communication are limited and who is sent to sit at the back of the class becomes a frustrated child who needs patient and considerate teaching to recover his self-esteem and express his latent intelligence.
