I read an article about the massive earthquake's tragedy. It was about a father who lost his two precious daughters. It was very heartbreaking story actually. The day before the earthquake, one of his daughter asked him that if she can sleep with him that night. He refused with no reason, just said, "not for today".... Next day, she was taken by tsunami. How can I understand his feeling? How much he regret it? If I were him, I'd never be able to forgive myself..it's gonna be left huge and deep scar in my heart. So I always try not to regret. But this is very hard. I know.
