Mrs Pigeoncot has been writing out a family genealogy. In doing so, she appreciates the presents from her relatives, such as greeting cards to the silver wedding that she is just celebrating with her husband Wilfried. Silver pitchers, candlesticks, musterd pots dishes and bowls have been gathered on the fireplace mantelpiece. Suddenly there comes an unexpected visitor, a young man by the name of Wilfried, as it is a common name in the family. To recognize one from another, the men in the family usually have a nickname. A charming young man is put up in the guest room. Later in the evening, Mrs Pigeoncot gets shocked, finding out that the man is most probably Wilfried, nicknamed Pilferer, who, at the age of twelve, stole an embroidery frame from her relatives. An energetic lady makes her husband search the guest's room after he departs to the bathroom. The suspicion has been confirmed - a small silver cream jug is in his suitcase. Pigeoncot placed the jug among the other identical seven jugs. At dinner, the guest hesitantly complains. He brought a present for the hosts, but it got lost while he was in the bathroom. He felt silly to give them another eighth jug, so he planned to replace it by a different gift. Mrs Pigeoncot, dying of shame, realizes that she mistook Wilfried, the Pilferer for Wilfried, the Diplomat. She sends her husband away from the lounge, explaining to the guest that her husband suffers from kleptomania. Saying so, she provided for her husband's immortal negative reputation in the family.
