It runs and runs but can never flee. It is often watched, yet never sees. When long it brings boredom, When short it brings fear. What is it?

Why this works

The answer to the riddle is "Time," and it fits perfectly due to its intriguing characteristics. The phrase "It runs and runs but can never flee" refers to the continuous passage of time – it seems to move forward endlessly, yet it’s not something that can escape. The line "It is often watched, yet never sees" captures how we constantly monitor time (like checking a clock), even though time itself has no consciousness to observe anything. The contrasting feelings associated with time highlight its dual nature: when time feels long, it can lead to boredom, while a short time frame often creates a sense of urgency or fear, such as before a deadline. This clever play on the various aspects of time makes the riddle engaging and thought-provoking!
