Mine was years ago, I was left in charge of little brother who was a real joker, his favourite trick was to run out of our back yard round into the next street to knock on our front door then run away and hide. Unknown to me the local vicar who my Dad knew well had come round and knocked on the front door, with little bruv nowhere in sight I assumed he was up to his usual tricks, so I yelled "Go awayI know what you're up to!" This happened several times until I got fed up and bent down to look through the letter box supposedly at little pest of a bruv, only to have a tremendous shock as I came eye to eye with the vicar who wondered what was going on, and decided to look through the letterbox too! Was my face red!
