A good example for this just last night. I had a doe walk in from downwind at 15 yards. She blew and stomped but casually walked back away. Not 10 minutes later here comes four more does from the other direction upwind and they were all goofy too blowing and so on.I knew I didn't stink that bad and later realized that three young bucks had these does all pissed off by harrassing them all day and for the hour or so I watched them. It depends on the situation, but you can never be 100% sure it's you they are alarmed about.
