My hole in one

I was playing a practice round on my high-school golf team with my friend and coach. We got to the 141 yard par 3 eleventh. I grabbed a nine iron and tried to hit it light and it went right at the pin. I always play very quick so I was putting my club back in the bag before it even hit the ground. I got up to the green and thought it had went long, so I waited for my playing partners to chip because they both hit it short. Then I couldn't find the ball and my coach told me to look in the hole. It was in the hole.
