well, i often see deer when traveling through the woods and lately they let me get really close, like within 10 feet. one day i was waiting for a doe to pass me and she began eating twigs above here and foraging, so i waited. she started walking towards me and i slowly backed away but she continued walking. so i picked up my speed and walked faster, then i was running. by this time she was at a slow trot following me. she finally walked away when i was about 50 feet away. so is this curiosity, or aggressive behavior?
