If I won the lottery, I would buy a house for my family, so we don't have to rent one.
Then I would buy myself a house in Kansas, and use lots of money on traveling to see my family every weekend.
I would buy a swimming pool, with a hot tub attached.
Next, a horse, 3 puppies, and lots of kittens.
I would buy one of the new laptops that is almost as thin as a piece of paper.
And I would get lots of clothes and accessories and perfumes.

If I wasn't so dang practical and loyal to my family, and if I were not a minor, I would do all of that! (Providing of course that I actually won the lottery....)
