A friend lent her paperback copy of 'Mrs Calcott's Army' to a dear friend of hers who has been very ill, and is going blind. Her husband reads it to her in the evenings when she's in bed. He's enjoying it so much he doesn't realise she's nodded off, and goes on reading, and has to go back a few pages next day. He wants to know when the next one's coming out.
It's lovely to think that my words are giving pleasure to people going through difficult times.
