A real thank you

Thank you! Two simple words we say many times during the day. However a real "Thank you!" is being rarely sad. The one where you look another human in the eye, understand where she comes from and let her know it was more than just appreciated.

The noun "sonder" is defined as "The profound feeling of realizing that everyone, including strangers passing in the street, has a life as complex as one's own, which they are constantly living despite one's personal lack of awareness of it"

At the same time everyone else around us is living a life wishing for the same simple thing as we do. A real thank you.
