I am so sorry about your son.
My 15 year old son lost a good friend a few weeks ago. A freak accident, one of those thing that will never make sense except to say "it was time for God to call him home."
He was truly a good kid. He was the leader and the workhorse.
His parents lived every parent's nightmare and God knows as much as I wanted to have magic words, there were none. I pray for you as I pray for them, May God comfort your heart.
