Drizzle is when the sky gets dark and gray, and tiny little drops of rain start to fall from the clouds. It's like the clouds are crying really tiny tears. Drizzle doesn't usually last very long and is less intense than regular rain. You might not even need an umbrella because the drops are so small, but it's still important to stay dry and warm to avoid getting sick. Think of it like someone sprinkling drops of water from a watering can instead of pouring a bucket of water on your head - it's just a light sprinkle!
