Stop trying to grow up so fast. 
It's not worth it, I promise. I tried to grow up too fast, & I regret it so much.
You won't always be in elementary school where you only have 1 teacher, you'll grow up to have several blocks/periods throughout a day.
You won't get a Tuesday folder to bring home for your mommy to sign.
You won't get stickers for having good behavior.
Your bestfriend won't be the innocent girl you've always known. In fact, you'll grow up & probably not even talk anymore.
You won't always be short enough to play on the playground at McDonald's.
You'll lose all your baby teeth, no more Tooth Fairy.
You'll stop believing in Santa & The Easter Bunny.
Instead of playdates, there'll be wild parties.
You'll be so stressed out from all the homework you'll have.
You won't be 'cool' if you don't have designer clothes.
If you're fat, you're made fun of. If you're skinny, you're made fun of.
You'll have lots of heartbreaks.
You'll worry a lot.
Don't be embarrassed of your mom, she won't always be arond. She'll turn out to be your bestfriend; the only one you can turn to. Appreciate her.
Please don't grow up too fast.
