Where should I never take a first date?
Well, when you're going out on a first date definitely don't take them to a dark alley. Also don't take them to a family function, because this could be uncomfortable for everybody involved. You'll be uncomfortable, they'll be uncomfortable, your family will be uncomfortable and also people may have preconceived notions, such as "Oh is this the person that you're going to marry? Is this the person that's in your life?" when they may not be, so don't do that.
