So, the check that needs to be mailed first thing tomorrow is sitting on your desk at the office, only you’re sitting at the airport preparing to take the red-eye to Tokyo (or Boise).
If you text your boss right now, you’ll wake her up and who knows if she’s even going to the office tomorrow. If you wait until morning, you’ll forget, not to mention by the time you arrive at your destination, your timezone might not even contain a morning.
Luckily, you can leave a crumm at your office so the first person that arrives, whomever that may be, will get your electronic sticky note and mail that letter.
Crisis averted, you’re a breadcrumm hero.
