The whys of this universe

An oval mirror with a golden frame on a cream table; inside, a large stylized eye with a navy outline and an amber iris looks straight ahead, perfectly still, while a pale, slightly offset double of the iris fades beside it, like an unseen movement.

Why do you never see your own eyes move in a mirror?

Évélie is the universe of the obvious we'd never questioned. Here you find why we say "hello" on the phone, why mirrors flip left and right, or why a tennis stadium carries a pilot's name. Behind each everyday detail there often sleeps an old convention left in place by habit.
