Unlikely hole in one

I wasn't feeling up to par and didn't even want to play golf, but my wife persuaded me to play. I wasn't playing well, either, but on the par three fourth hole (playing 171 yards) at our club, I had an unusually smooth swing off the tee. My ProV1 rolled down the middle of the green. We couldn't see the cup from the tee and when we got to the green, I saw two balls on the green and one off. I thought I might have rolled off the back of the green but didn't find my ball there. One of our playing partners looked in the cup and there it was! What a thrill! You never know when it will happen.
