Love is like the icing on a cupcake

While driving to our weekly swimming lesson today:
Isla: "Mum, I love Nana Linda the best".
Me: "That's great honey. Why do you love Nana Linda the best"?
Isla: "Because she lets me taste the icing when we make cupcakes and she makes cupcakes with me when it's not even my birthday".
Me: "But we make cupcakes all the time at home too".
Isla: "Yeah, but last time you didn't let me taste the icing". (She didn't even want them iced if I recall..)
Me: "Sorry honey, next time I will let you taste the icing okay?"
Isla: "Thanks mum, but I just think it's best if I live at Nana Linda's".

A case for the family court perhaps?
