Power-walking to your car on the way to work, your phone is in one hand, your briefcase in the other. You feverishly text a reply to a friend's dinner invitation while mentally reviewing the evening's schedule — call your mom, stop at the bakery for a loaf of bread, fill up the tank, take the dog out for a walk — as your inbox alerts you to a new e-mail from your boss and your favorite news app updates you on the latest stock market movement. Meanwhile, the weight of the papers in your briefcase reminds you of all the work you need to catch up on before your meeting at noon. Database updates, system training, progress reports — and, boy, your car could really use a washing. You reach in your pocket, desperate to get started — except you forgot your keys.
