To hope or not to hope?

I pitied her.

Did she gave up just because she was waiting there all alone for several hours but he did not turn up?

I admire that spirit of her for waiting at that place even though waiting in vain, or perhaps she thought he would come?

I never wait.

Because waiting is like hoping for a positive outcome.

When a person hopes,

the probability of getting the positive outcome is 50% while negative is another 50%.

So why hope when the chance of getting disappointed is so high?

I stopped hoping since i-dont-remember-when-anymore.
