If you are looking for a thank you when you have done something for someone, forget it. The motivation is all off. <br />
Do something without expecting something in return. Then you won't be disappointed.
A thank you would be nice especially if gone the last mile for someone.<br />
The author is not asking for bended knee gratitude just a little common politeness and respect.<br />
It is nice to see someone so young learning the value of thank you<br />
You feel disappointed?............ because you feel a need to be appreciated?<br />
