Today, my 6 year son and wife opened the door to an ex-prisoner going around with a tatty piece of paper telling people he is selling thing. My wife and son didn’t know how to respond, luckily I was working from home and heard the door and told the guy ‘We don’t buy from door to door sales’.
He is most likely working his way to you.
Next time just say you are not interested and don’t let people pressure you to buy things that you don’t need!
