It is obvious that "your" deeris a "suburban" deer and is not worthy of our pursuit. Look how relaxed and cozy he is.
I have attached a picture of a "real" deer out in the wild. See how his ears are pinned back. This guy is a walking powder keg ready to explode at the next shift of the wind or leaf fall and likely won't quit running until he is in the next county.
Yes, my friends, there is a difference, and I've got pictures to prove it.
