We have a sign in the window, from the police, stating that we don't buy or sell to anyone knocking on the door. Why do people think it's OK to ignore it. Window cleaners, gardeners, electricians, all sorts of tradesmen just take no notice. Last week, someone put one of those make up catalogues through the door, for collection today. I never buy anything from them, so I left it on the hall table to put out today. Left it on the doorstep and an hour later, there was a knock on the door. Of course, it was for the catalogue which had disappeared since I put it there. He was very annoyed and equally annoyed that I didn't want to order anything. Why do I feel bad? I didn't ask for it, didn't want it and am I unreasonable in being irritated. I know that people are trying to make a living, but it feels intrusive and I don't want to be made to feel guilty for not buying something I didn't want.
