i thing im going to rewrite one of the beautiful emails from  seth godin

waves are free
when someone lets you into the flow of traffic ,

 or holds a door 

or takes a second to acknowledge you it's possible to smile and offer a wave in response.

this , of course cost you nothing

it creates a feeling of connection , which is valuable.

it makes it more likely that people will treat someone else well in the future.

and it might just brighten your day.

the simplest antidote to a tough day is generosity.

waves are free and smiles are an irresistible bonus(prize , gift)
