What is smile?

A smile is when your face shows happiness because you're feeling good inside.

Imagine you just got a big scoop of ice cream on a sunny day, that's so good, your mouth starts to curve up at the corners, and your eyes light up. That’s a smile!

When something makes you happy, like getting a toy, eating candy, or playing with a friend, your brain sends messages to your face. Your face muscles, especially the ones near your mouth, get busy working to make that curve on your lips. That’s how a smile happens.

Smiling is like saying “I’m happy” to everyone around you. It helps you feel closer to people, just like when you high-five a friend or share your snack with them. A smile can make someone else feel happy too, even if they didn’t know something good was coming!
