Envelope – It starts and ends with the letter “e”, and contains a letter (like a written message) inside. This riddle is based on double meaning: “letter” as a character, and “letter” as something you mail.

There are no stairs – Since the house is one-story, it has no need for stairs. The mention of “redwood” is meant to distract you with irrelevant detail. It’s a classic case of camouflage through unnecessary information.

Your name – You own your name, but other people say it far more often than you do. It’s a classic riddle about ownership versus usage — even though it’s yours, it’s most frequently used by others to refer to you, making it feel like it’s used “more” by them.

The living room – A pun on the word “living.” Ghosts are considered the dead, so they would logically avoid places associated with the living. It’s a joke that works by taking figurative meaning and making it literal.

“An apple a day keeps the doctor away.” – The bus driver gave her 7 apples, one for each day he’d be gone, as a playful way to “keep the doctor away.” This is a pun-based riddle, relying on a well-known proverb and interpreting it literally as part of a clever love triangle joke.

Yesterday, Today, Tomorrow – These are real consecutive days that describe time but are not actual weekday names. The cleverness lies in breaking away from the literal interpretation of calendar days and instead focusing on how we talk about time conceptually.

David – Many people assume the answer is “Pop” (from the Rice Krispies slogan: “Snap, Crackle, Pop”), but the riddle clearly says “David’s father”, meaning David is already one of the sons. The trick here lies in misdirection through pattern expectation, when the real clue is right in front of you.

A coin – Coins have a “head” (usually a face of a person) and a “tail” (the opposite side). Many coins (like U.S. pennies) are copper-brown in color. Since it’s a flat object, it naturally has no legs. The riddle uses physical metaphor to describe an inanimate object in human-like terms to mislead.

Starting – It’s a sequential wordplay. Each time you remove one letter, the remaining letters still form a valid English word: starting → staring → string → sting → sing → sin → in → I. The brilliance of this riddle lies in how smoothly it transitions through actual words, showing how language can compress logically.

Footsteps – This sounds paradoxical because “taking” something usually means removing or consuming it. But here, “take” refers to taking steps. With each step, you leave behind a footprint. So the more you walk (i.e., take), the more you leave traces (i.e., footprints) behind. It’s a clever play on multiple meanings of the word “take.”
