THANK YOU IS COMMUNICATION FOR PEOPLE

Thank you acknowledges an act someone does for someone else with no
expectation in return.

When we open a door, give up a seat, let someone pass or do an
especially good job we are giving a gift. Not a birthday or holiday
gift, but a gift none the less.

We are acknowledging someone else is in the doorway, on the road, in
the office or on the bus. We are saying, for the moment, allow me to be
deferential to you, to your needs. It is a gift of kindness.

The reality is when we perform these gestures of recognition they are
done willingly and the benefits received are all in the doing.

The completion of the dialog is the expression: thank you.  That
expression says, I know what you did for me. I know in its own small
way it is a gift and, while I appreciate it, more importantly I
recognize in that one split moment in time you are a part of my life
and I welcome you into it.

Don't ever overlook a thank you. It is a human expression that no
other species enjoys.

Let's not lose it.
