Do you have expectations from others?

It is human that expectations arise in one's mind. If others fulfill those expectations, you would be happy. In case those expectations are not fulfilled, you would feel disheartened. On the other hand, if you have no expectation from someone and he does something for you, you would feel happier than in the expectation scenario. If he does nothing for you, you would not feel disheartened.

It is better to let go of expectations from others.
