The other back yard

Lately I have been letting Emma play in our back yard with Sanford while I feed Georgia or clean the kitchen. She knows she is supposed to stay where I can see her and she follows the rules well. Today she said "I want to go to the other back yard." What? Eventually I figured out she meant the front yard! So we are learning that leaving the house is called outside, the outside in front of the house is the front yard and the outside behind the house is the back yard. Who knew it was so complicated!
