Why is this the answer?

The answer is reflection because this clever riddle describes exactly what happens when you look at yourself in a smooth, shiny surface like a mirror, a window, or even calm water. A reflection is an image of you that appears in that surface, and it is a super interesting scientific event caused by light bouncing back. Let us look at the clues one by one to understand why this is the perfect answer. The riddle starts by saying, "You can see nothing else, When you look in my face." Think about when you look closely into a clean mirror. You are focusing only on the picture of yourself that is staring back at you. You might see the wall behind the mirror, but the main thing you see in the glass is your own image, which the riddle calls "my face." The next line is, "I will look you in the eye." This is a fun and simple clue. When you look into a mirror, your reflection always looks right back at your own eyes. It is like an imaginary friend who always matches your movements. If you blink, it blinks. If you smile, it smiles. It follows you everywhere you move because it is just a copy of you. It is always ready to look you in the eye, no matter what you do. Finally, the riddle says, "And I will never lie." This is the best clue because a reflection is a true and honest copy of whatever is in front of it. It cannot hide or change anything about you. If you have peanut butter on your cheek, the reflection will show peanut butter on your cheek. If your shirt is wrinkled, the reflection will show a wrinkled shirt. It always shows the truth about how you look right now, making it the one thing that will never tell a fib. This is how the clever riddle leads us straight to the correct answer, which is reflection.
