Regrets...

It is really painful to see someone feeling regret over things he/she had not done, or feeling remorseful over things he/she had done. The sight can really break your heart and no amount of consolation will ever ease the regret or remorse. And if they are given a chance to redeem themselves, not in a direct way though, will they realize it?
I believe that everyone is always given a chance to redeem themselves. But chance may not be outright obvious, and they might only realize it after that.
And hopefully, even when the moment is gone, they will have a better memory of the redemption they had.
