book fair

Ms. D said that I need money to buy books today.
The book fair is today, huh? Do you want me to go to school and help you choose a book or do you want to buy a book on your own?
I'll buy a book by myself.
How much money do you think you need?
Hmmm... 30
30? That's a lot of money, hun. What about I give you 10.
But, the books are really expensive.
she thinks for a moment, I have no clue what was going thru her head but she said, OK, I guess 10's ok

I wonder what kind of book she'll get or if she gets one. It takes her forever to choose a book. I didn't have a 10 in my wallet so gave her a 20 instead. Then, told her that, she has a 20 but she can only spend 10. Hubby laughed as I was explaining this, she doesn't understand the concept of money, yet. But, who knows, kids are smart. I doubt though if I get my 10 back, I bet, she'll come home this afternoon with her backpack filled with books.
