One should not have expectation from any one except oneself.It is my personal experience.If you have expectations from others and it is not fulfilled then you tend to get hurt.You keep expecting from your friends ,family, colleagues,relatives,loved ones and if they don't live up to your expectation you get disappointed .More you have expectation , more you tend to get hurt when things are not done according to your expectation .So,it is better not to have expectation from anyone.I feel expectation from others is indirectly demanding and forceful.
