My first bow kill ever,over thirty years ago, was a clean miss right underneath her. She jumped back, startled to be sure, and just stood there for probably twenty minutes on high alert. Then she suddenly relaxed and walked in front of me broadside inside of twenty yards. I had enough time to stop shaking, calm down and refocus for a good shot. While I've not experienced anything else similar I'm sure it's not an uncommon response. Rather than run headlong into an unknown threat, from who knows where, I can imagine a deers instinct at times is to hunker down and rely on its senses.
