Elevator etiquette

Sharing an elevator with someone instantaneously creates some sort of a social black hole. What do you say? Where do you look? There’s the obligatory upward glance at the flashing floor number, but then you must make sure to never make eye contact, nor even remotely look in the direction of the person next to you. You ride in silence, constantly debating whether or not to comment on the slow speed of the elevator or how it must be “stopping at every floor today!” chuckle, chuckle. No, you hesitate, and instead ride in this socially awkward, sterile metal cage up to your floor where you let out a sigh of relief at surviving yet another socially confusing episode. And then you realize you dropped your keys back on the first floor and must go retrieve them.
