When you're tired, your brain gets a bit lazy. It can't think clearly anymore, and that makes you feel grumpy or sad. Imagine your brain is like a robot, when it runs out of battery, it starts acting weird.
Examples
- After a long day at school, you snap at your brother over something tiny.
- You’re sleepy on the bus and start crying because someone talked to you.
- Your mom says one thing, but you take it as an insult and get angry.
