I noticed especially old persons will be very happy if somebody enquires them about their well being. We will notice that happiness on their face. It is a good practice to say Namaste when we see a elder person for the first time on a day. That will make the other person happy and the blessings he showers on us will have a really good effect on us. We should teach these good manners to our kids from their childhood so that they will get habituated to these good habits.
