I phoned to arrange an appointment with a family; it went like this….

Woman answers call
me   ‘hello, is Doug there?’
woman ‘no, nobody here is called Doug’
me ‘are you sure’  (stupid bloody question)
woman ‘yes, we don’t have a Doug here.’
Luckily I asked her the next question… ‘do you know a Mrs xxx’  (a person connected with the call)

The woman replies ‘yes I am her daughter.’

On my booking sheet, I had abbreviated the word ‘daughter’ in large scrawly letters, which looked like Doug  (Daug).
