The mouse

Mom: Ally do you want to place a computer game with Curious George.

Ally: Yes!

Mom: Okay we are playing Zoomazing. We have to use the arrow keys to move the animals to their homes. I will help you.

Ally: Mouse!

Mom: this game doesn't use the mouse. we have to use the arrow keys. point your finger and I will help you.

Ally: No! Mouse!

She takes the mouse and in 5 clicks manages to shut the whole computer down.

Then turns to look at me.

Ally: " No mouse"

Mom " That's right Ally, we shouldn't have used the mouse"
