However, at the end when we dont get expected response we feel bad. And, started thinking about the reasons of their behavior or answer. We are hurting ourself in this way. Thus, it is better to aviod negative thinking. Do not expect from others. Live your life beautifuly. Do your work and dont expect in return.
