A story about a leech

Since I have been too lazy to blog, I am just gonna post a short story this time to keep my readers happy, or pissed off (assuming if I do have some readers).

This story was inspired by someone really close to me.

Once upon a time, there was a kind and beautiful women in an unknown kingdom. However, fate was not on her side when she gave birth to a leech instead of a human boy. Her heartless husband and the father of the leech left them not long after. Nevertheless, she showered Leech with love and care and gave him everything that she could afford by working non-stop day and night. Leech become strong and huge and turns into a real man when he was 25 years old. He even got married and have a son, wtf. The women, now old and retired was overjoy to see her only son turning into a real man and having a family on his own. Alas! The son was ungrateful, treat the women poorly and take advantage of his old mom in many unspeakable ways.

What should be the ending of this story? Please share your thoughts and drop me your comments! =)
