Tonight as I said goodnight to Ella, she was looking at me with a sort of blank expression.
Me - Why are you looking so serious?
Ella - Mum, this is actually how my face is. Because if I smile that's not how it is. If I smile, see [flashes a quick smile]... and then it goes like this [looking serious again]. And this is actually my normal face.
Me - That's fair enough, sweetie. Goodnight.
