As a master of the ancient art of napping, I've developed a 3rd technique for napping in motion. It's a delicate balance of timing and stealth, but trust me, it's worth it.
Step 1: Choose your napping location wisely. A busy coffee shop or library is ideal, as the constant noise and activity will keep you on your toes.
Step 2: Position yourself in a strategic location. Near a window is ideal, as the sunlight will keep you from dozing off. Plus, you can people-watch to your hearts content.
Step 3: Master the art of the 'napping smile'. It's a subtle blend of a smile and a scowl, used to ward off any would-be napping disruptors.
