What makes a person?

What makes a person who they are? Is it the way they handle things, what they do with their time, their values? Is it what they work, how they look like, their dreams? Or tiny things that aren't just as small, how they talk, smile, Lough, smell, how their eyes crinkle when they Lough, the spark in their eyes when talking about a thing they love, the way they dress? What perfume they use, how they tuck their hair behind their ears or play with their necklace when they are nervous? Their voice when they tell you a secret and whisper, when they sing or sigh? The way they grab your hand when they're excited or the magic they believe in? Their heart-beat, habits, teeth, eyes, hair and their way of thinking? Their gasps, squeals, screams and silence? Or is it how they treat you? Is it how they sit and listen, reassure, joke and show you love? Is it how they appreciate you, nickname you, bother you? Is it that they understand when to be silent or loud? Is a person in or out of themselves?
