The riddle asks: What can you see every day but can never see tomorrow?
The trick is in the meaning of “tomorrow.” We can talk about tomorrow, plan for it and imagine what it may bring, but by the time it actually arrives, it is no longer tomorrow.
The answer is: tomorrow itself.
When the next day arrives, we experience it as today. There is always another “tomorrow” ahead of us, so we can never actually experience a day while it is still called tomorrow.
This is more of a word-and-time riddle than a visual puzzle. Its simplicity is what makes it effective: the answer seems obvious after you hear it, yet the wording can keep you guessing for a while.
