There's a son who really hated his one-eyed mother. Every time his classmates went to their house, he would tell his mom to hide. After graduating college, the son abandoned his mom and wrote a letter for her that tells how much he hate her. After two years, the son became a doctor and had two kids. One day, a one-eyed beggar went to their house and he knew that it's his mom. The beggar left a letter...

"My son, I know you hate me of being a one-eyed mom but when you are one-year-old, you had an accident and I gave my one eye to you for you to see my love."
