Riddle: Wingless, it flies, Never, it dies. Trickling slowly, Bringing all lowly. What am I?
Answer: "Time" - Reasoning: Time can both fly by and trickle slowly, depending on how exciting or boring a situation is. It doesn't die, which hints that its not a physical entity, more an idea. And "bringing all lowly" represents how all things decay and fall into a state of entropy over time.
