Why wouldn't you get mad that the deer didn't stop in the spot your arrow was directed? I acually missed the largest deer I have ever shot at with bow or gun twice at 25 yards about 5 years ago. After the first shot the "what could have went wrong' was going through my head so since I shot high the first time I aimed low the 2nd and hit right were I was aiming, low. Didn't realize what had went wrong until my way home, I had failed to bend at the waist which changed my release point. I can still see that sucker, looked about 4 feet from back to belly. No way I would ever miss that same opertunity again. This year I shot one at 42 yards through an opening about 6 inches wide. I had to bend about half way over to get the deer in the little opening, you just never know.
