State the Obvious

If you want to be annoying or unhelpful, state the obvious. When someone is in the arena doing something difficult stating the obvious from the stands seems like the helpful thing to do.  

“You need to hit the ball on the green, if you keep slicing it you’ll never make par, you need to learn to have more control.”

The golfer’s number one goal is to get the ball in the hole. He is doing everything he can to hit the ball where he is aiming.  Highlighting the undesired outcome makes you look like a fool… unless you are playing for money.
