The special day is finally here! Mom and Dad have given their blessing and you'll be spending a night away from the house. No, it's not a sleepover. You're going to the airport. To fly somewhere. So why are you wearing brightly-colored sweatpants, slippers, and a sleeping mask?
"Did you pack your own bag?," the TSA agent asks. And you did, but only with Heath Ledger DVDs and Electronic Dream Phone. Also, you're half-asleep and drooling, the side effects of dressing for a slumber party.
Listen: When you travel in an airplane, you're actually a member of the public. You're actually going to interact with other humans—strangers, in fact. Dress like a real person, not a college student who just stepped out for a dime bag and a Slurpee.
