I think you’ll agree, we have a directional problem 

Remember your first day of classes at university? You arrive on campus with your bag brimming with materials, excited for a fresh start. Your first class of the day is in the business building, room A311. When you enter the front door, you have no idea which way to turn. Students and administrators are rushing about you on their own way to their own destinations. You hesitantly turn down one hallway and find yourself in front of room D110. Does the D denote a wing of the building? Are you looking for a room on the first floor since you’re in an A or the third floor since it’s room 311? What does it all mean? Where are you supposed to go? The panic starts to rise as the clock ticks.
