Mirroring is when you naturally match the other person’s behavior, imitating their gestures, speech patterns, and so on, but it’s not the same as copying someone. It usually happens when you’re comfortable with each other and often goes unnoticed by both of you. I believe it’s mostly a subconscious action.

It can have a romantic element to it, but you can also feel it with close friends. And mirroring alone doesn’t define chemistry, it’s more about the overall feeling, as I mentioned.
