Humans are all selfish

I just learn something new today, All humans are selfish. The only difference is how far they will go to get what they want.

I am selfish. I work and often try to make full use of my company resources for personal agenda. Dun need to quote any example, I think everyone of you does the same thing in same ways or another.

Since everyone is selfish, I can't blame him for being the same right?

He have long mentioned his situation. I know things are impossible, but why do I still feel sad that he is just taking advantage of the situation and enjoying both world?

To him, I give what she can't provided. But what I want, he can never give. I shld be more wise to realise that I am just getting myself hurt.

Disapointment comes when one's expectation is not met. Does that mean I am hoping for certain something from him?
