Yawning is like a magic breath that helps you feel more awake. When you’re tired, your brain gets sleepy, and yawning sends a fresh wave of energy through your body to help you wake up. Imagine your brain as a little sleepy dragon, yawning is like giving it a big splash of water to make it roar again.
Examples
- You're sitting in class and suddenly yawn because your friend yawns.
- Your dog yawns when you wake him up in the morning.
- You’re watching a boring movie, and before you know it, you’re yawning too.
