Say who???

On my way up to Fraserburgh this morning, I saw a deer in a field.
I stopped the car and walked along the road a bit. However, before you could say " Andy Murray", she was off and leaping over the fence you can see at the back of the photo.
Just what made her run away?
Was it the noise of the car?
Was it my scent? I had just had a shower!
Or could it have been me shouting out " Smile!!"
