Electrons

There's always something you couldn't change
There's always something happening which is out of your control
That's because we expect something, we have faith in something

Friend said, can we just live without expectation? I think, that's hard. Very tough.
Things happen for a reason.
We do something and we hope to get something in return. It's very chemistry.
You gonna donate some 'electrons' and accept some 'electrons'.
Things will only work out when there's an electron donor and electron acceptor.
That's how we are bonded. When we donate, we need to accept. That's why we always expect something.
It sounds simple but how many people can really work this out? How long the bonding can last?
