Why don't property companies let salesmen go in to sell, and we are also serving the society and reducing social pressure? We have no destructive thoughts or actions!

Why not look at this problem from the perspective of residents? When we are at home, we all want to have a good rest. When we finally had a rest, your salesman knocked at the door. What would you think if a stranger knocked at the door just after you took a nap? Think about it the other way around.
