Amaia: Mummy, can we buy bananas?
Me: Sure, but I thought you didn't like bananas?
Amaia: I don't but it is Lily's first birthday tomorrow and she likes bananas.
Two aisles further on...
Amaia: We need a cake mix.
Me: What for?
Amaia: Well, we need to celebrate her birthday too! It wouldn't be fair if we had to have banana, would it?
I guess she had it all planned out so she could get some cake! And it worked!
