I have moved 19 times as an adult, and met all sorts during these moves. Once we had sold our house and this man came and offered us first of all £5000 and then £10000 more. I looked him in the eye and said but I have given my word, he said but you could make more money. I replied that if you were such a sleazy person prepared to go to such lengths, you would be totally untrustworthy and showed him the door. I also rang the estate agent , who was a local firm and had a good name, and told him what had happened. Yes I got less money but can look myself in the mirror and know that I have stuck to my principles I also knew someone whose agreement was that the almost new staircarpet would be part of the sale. So 3 days before the move they said they didnt want the carpet,assuming that they would get the carpet for nothing. Ha ! picked the wrong person. She checked again that they didnt want it etc, and then stripped the carpet and gave it to a charity, Took the spare rolls of wallpaper she was going to leave etc( I always leave the spare wallpaper, and a little book with size of room - how many rolls of wallpaper, the electrian, plumber etc etc so that they have somewhere to start . It has always been appreciated )
