Ellie: (with a pillow on her lap) Mommy, is this the size of a computer?
Mommy: Computers used to be that big but now they're much smaller now.
Mommy: When they made the first computers they didn't know how to make them small or even smart.
Ellie: What do you mean?
Mommy: The first computers couldn't do much. Computers haven't always been smart. When Gramma was a child, they didn't even have computers.
Ellie: WHAT??? NO COMPUTER???
Mommy: Nope. They invented computers after she grew up.
Ellie: But then how did people buy stuff from the internet?
Mommy: They didn't. If they wanted something, they would have to go to the store. And if the store didn't have exactly what they wanted, they would have to choose between whatever the store did have.
Ellie: THAT'S AWFUL!!!
Mommy: I know!
