Writing letters requires a number of basic skills.
These include writing, intelligence and imagination, none of which I appeared to have mastered when I rediscovered a pile of 50-year-old letters sent home to my parents from boarding school.
Letter writing is a dying art. The ones I found suggest that the art died long ago.
If you're going to write a letter, make sure it's worthwhile because what you record on paper endures.
It's there for ever, or at least until the recipient throws it out - or dies, at which point you may rediscover it and, if you're like me, cringe.
