There are three kinds of people in this world: Aisle, Window, and Middle.
Aisle is the hyperactive extrovert. They regard Middle and Window as prisoners of their own domain; their ability to socialize, stand, or even request a glass of water is entirely dependent cooperation from their rowmates to the side. Are Middle or Aisle sleeping? Well sorry Window, looks like you can’t use the bathroom for the remainder of this 7-hr flight.
Aisle, on the other hand, is free. They can control their own destiny. Surrounded by constant stimuli, they find themselves exploring every opportunity they can scrape from the situation. There’s people watching: what’s the couple in 14A/B fighting about? Who’s child is jamming crayons into the ceiling fan? They can stand, stretch, use the bathroom, or acquire complementary snacks whenever they want. Want conversation? They’re surrounded on all sides by other groups of travelers.
Have you ever heard the pilot come on the PA, frustrated: “For the third time people, the seatbelt sign is on for a reason, return to your seats and stay there.” That’s Aisle. There are no rules for them. They’ll reluctantly return to their seats for a moment, but only to stuff their seat-back pockets full of all the treasure they’ve collected in the cabin. Leg twitching excitedly, they’re already planning their next move.
