Maybe the other person is just an elderly man, and you are a little disdainful to talk to him more. After all, young people have a world of young people, but this mentality is not good for your work. Sales work like real estate needs to contact and accommodate customers of different ages and different mentalities, regardless of whether the result is successful or not, but the opportunity cannot be missed. And I think this old man may become your potential customer, but you missed him, so you'd better take care of yourself.
