Heard the story of the boy this morning. His dad was running the marathon and the boy ran to give his dad a hug as he was crossing the finish line, then as he went back to his mum the blast went off, the boy was killed and his sister lost a leg! Can't comprehend how it went from utter joy one moment to lives being shattered a moment later. Really does make you think that you never know when you life will be changed forever.
