Why Do We See Infinity in a Mirror?

Imagine you and your friend are standing in front of a mirror, and the mirror is facing another mirror. You both see each other again, and again, like a game of tag that never ends! That’s how we get the illusion of infinity: it looks like there are more and more reflections going on forever. Each reflection is just you or your friend looking back, but because they’re in mirrors facing each other, it feels like infinity is hiding behind them.
