A poor boy asked a woman for water but she instead gave him a large glass of milk. Years later, when the woman fell gravely ill, the doctor who was called in to help was the same boy, now a doctor, who remembered her kindness. After a long battle, he was able to save her life and when she received the medical bill, it was marked as paid in full with the glass of milk, showing how small acts of kindness can come back to help in unexpected ways.
