I defintely agree with you. Infact I do these things all the time
even when I am on the phone. MY goal in life ,is to meet one new person everyday. And yes it does feel good !
I also feel that if you are a good person trying to help others,
more good comes back to you. I remember, one day about
3 years ago, I was so sad because I was using a cane.
It was such a terrible time for me, because my orthordics,
were made wrong. This caused a backache, hip and knee
pain that I could barely walk. On this day I was coming out
of a department store,still using my cane, when a very
handsome man, told me Hi and have a nice day! It was
like an angel trying to send someone to cheer me up.
