What flies without wings?

Why this works

This riddle plays on the concept of time as an abstract idea that "flies" or passes quickly, despite not having a physical form or wings. The phrase "flies without wings" cleverly contrasts the literal notion of flying—typically associated with birds or planes—with the figurative sense of how we experience time slipping away. So, while we often hear people say, "time flies," it highlights the paradox of something as intangible as time moving quickly in our lives.
