"Daddy, Do you know why I always remember bad things, bad experiences instead of good things? I just can not help it."
I puzzled for a long while, and said,
"You know, it is human's nature and survival's instinct to memorize bad things so that we could avoid the same mistakes again."
"We need to learn from God and pray for God to appreciate and tresure all the good things we had, to be a better person."
