Oliver Wood
He's been to 12 funerals, counting only the ones where he was the one grieving, he's lost count of how many he's been to to support a friend.
Seven of his year mates are dead and he's not even forty yet.
Nearly half of the people he played on the Gryffindor quidditch team with are dead. Or worse.
His little sister was force to endure things at Hogwarts that she still can't talk about very much.
He saw the dead bodies of his friends and allies.
He will never forget those horrible things, those numbers that haunt, the terrifying amount of people who died before their time.
He lived through war and will never let his children have to do the same. Never.
