Have you ever had that feeling someone was watching you?

I walked outside to do chores tonight and I felt like someone or something was watching me.  I walked halfway to the calf barn when I heard something to my left.  Scared the crap out of me. Up here you never know what you'll encounter in your backyard. I turned to see two deer standing right behind our camper headed for the garden.  I finished carrying my bucket of water out to the calf and went back in the house to fill it up again.  I grabbed my camera fully expecting the deer to be gone by the time I got back out to take pictures.  I walked around the front of the garage and through the pig pen.  As I got to the tree in the pen I looked up to see the deer watching me not even 20 yards away.  I was able to get a few pictures before they stomped at me and ran off, flags waving.
