While Malala’s and Latoya’s memoirs were written shortly after the events they write about, Roald Dahl was almost 70 years old when Boy was first published. In this snippet, he talks about his headmaster in primary school.
While it contains a description, this snippet’s not really about what his old headmaster looked like. Dahl is thinking more about his memory. He flags this continually with phrases like ‘I can remember’, ‘in my memory’, and ‘I have a picture in my mind’.
