I had a doe do that to me today. My blind isn't exactly a blind, it's a downed treetop. I put up camo net for full concealment, but the open end is toward the tree top. A doe walked up to me right in the middle of the tree, about 8 feet away. Of course I was turned the wrong way to shoot, so all I could do was sit there and hope. She stood there for like 3 minutes, looking and sniffing. When she left, she went about 20 feet away and bedded down behind a tree. She was still there when it got dark, so I shined a light over on her until she got up and left. I don't think she spooked, just got tired of the light.
