Hey, Sun?

Yes, Earth?

I need to ask you a question.

How do I get rid of my allergies?

But then how can you explain THIS?

Allergies?! planets don't have allergies!

On another, it's Really really Hot...

On another, trees are shedding...

And on the 
last, it's 
really cold!

They Aren't 
allergies.

They're NOT?!

Nope. It's science.

You see, as you orbit around me and spin at the same time, you are tilted toward me.

Wait-- I'm spinning 
all the time?! 

You'll learn about that in other books.

Because you are tilted as you spin,
there are seasons.
The side tilted 
toward me is hot, away is cold, and fall and 
spring are in the middle.

 

Uh... okay.

That looks nothing like me!
