What do you do when someone smiles at you? I bet that in most cases, you smile. How do you feel? I feel happier.
When I bike I am happy and that means that I am usually smiling. I get a lot of smiles back to me. Your smiles sets the tone around you.
I find that waves are like smiles in that if you give one then you get one.
PS. A "Hi" helps too.
