Humans sometimes are too greedy.
When someone do something good to you, you then expect others to do the same thing for you.
If others do not meet your expectations, you start to blame on them.
Why he can do this for me but you can't???
Humans, stop being so silly!
Be thankful and appreciate what you get!
They do not owe you one, so don't expect them to do everything for you.
It's your life, so it's your matter.
