Fame
Maybe one day Meryl Streep (or the celebrity of your choosing) will get sick and drive to the nearby drugstore where you happen to work. Maybe the two of you will share a moment, bonding as you fetch her cold medication. Maybe you'll be sad to see her go. Maybe, just seconds before she leaves, Meryl will run back to you, and offer you a starring role in her next film (which just happens to be about a struggling pharmacy technician trying to make ends meet).
Or maybe that won't happen.
Actually—yeah. That won't happen.
