What is smiling?

Smiling is when your face shows happiness by making your mouth and eyes look happy.

When you feel happy, something inside you tells your face to move. Your mouth goes up into a curve, like when you drink from a cup with a straw, it makes a smile shape. Your eyes also change, they get bigger and maybe even have little crinkles around them, like when you laugh while eating chocolate.

Imagine your best friend just gave you a big hug after a long day at school. You feel warm inside, and suddenly your face changes, that’s a smile! It's like when you press the "happy" button on a toy, and it lights up with joy.

Smiling is how people show they're happy without saying anything, just by using their faces!
