My son played football on the weekend. Before the match I took him to one side and gave him some fatherly advice. After the game I praised him, gave him some feedback and a big hug.

“I’m proud of you son.”

And I was.

In the evening I watched American Sniper. The controversial biography of Chris Kyle. A former U.S. Navy Seal. The most lethal sniper in U.S. military history. He had 160 confirmed kills.
