Stay Right Except to Pass!

What ever happened to staying to the right unless you were passing? Both on foot and on the road people are just parking their fat asses where ever they like and going as slow as possible. Do they see me trying to get past? Is this their way of making us all fat and lazy? I'm a sloth so you should be too. Or are they so self absorbed that they don't even see us? Common courtesy is a thing of the past. Get off your phone, put down your big gulp and get the hell out of the way!
