thankless

The month of December I decided to do a random act of kindness everyday until Christmas Day.   Most of them went well but several of the days didn't.  It still is a mystery to me how when kindness is shown to another person and I am saying going out of ones way type of kindness, that kindness is not returned.  In fact they expect more from a person.  Not even a simple thank you is extended.  It is very difficult to function in this world where ungratefulness is the main theme.
