Murphy's Pedestrian-Perks Law

Refers to the infuriatingly-common "lousy timing" occurrence of your seldom encountering the usually-hoped-for opportunities/pleasantries (i.e., neighbors relaxing on their front porches/lawns whom you can shoot the breeze with on your way by, pretty girls to hold hands with and "chat up for a few", sizable numbers of discarded returnable containers, etc.) whenever you're out for a stroll or otherwise leisurely traipsing around your local area on foot, yet when you either hitch a ride with someone or are "a man on a mission" in your own vehicle and thus you can't "acceptably" stop to avail yourself of any of these assorted "sidewalk delights", the roadsides you travel along will either be "chock-full of friendlies" or "Bottle/Can City", and so you'll be mentally "climbin' da walls" at having to agonizingly pass on by all of those much-desired goodies.
