In 2014, Irish parents Stephen and Josephine O'Donovan had to live through every parent's worst nightmare. Their six-year-old son Luke was killed in a hit-and-run accident. As a parent myself I don't know if I would be able to find any silver linings to that situation, but Stephen and Josephine have.

When Luke was killed, his parents sat down and decided to donate his organs so that even though their son was gone, others could have a chance to live through the gift of life.

"We always taught Luke that caring is sharing or sharing is caring. I suppose this was the ultimate example of that," Mr O'Donovan said.

It is hard to stomach the thought of losing a child, especially in a circumstance like this. The driver who struck Luke, 51-year-old Edmond Walsh, received a two year suspended sentence and was banned from driving for 10 years.

Luke's dad had been working in the garage when he heard a noise and saw something tumbling across his yard. That something was his son Luke.

The O'Donovans (apart from speaking on organ donation) are currently pushing for driver's license reform. Edmond Walsh had suffered serious brain injuries in two separate falls that left him with a child-like mindset, as well as underdeveloped movement in one leg and one arm. Even with these physical and mental restrictions he saw no changes to the status of his driver's license.

"This man, I would say, has the mentality of a child. He ran home to tell his dad, he got home to tell his dad. But Luke didn't get home to tell his," said Mrs. O'Donovan.
