A few days ago my son and I were doing our lessons and learning to read and write small words. We were doing those which end with the N, putting various consonants in front of them— bin, din, pin, and so on, we read. We came to the letter S and (I must admit) more for fun than for anything else I asked ‘Do you know what sin means?’ Martin looked at me and said ‘it is something we like very much, isn’t it father?’
