As I sent Ella off to bed, she asked me where "new cat" was.
Me - It's not here. It must be in your room.
Ella - It's not in my room.
Me - Look, it's not on my bed. Are you sure you had a good look in your room? Maybe it's under the blanket?
Ella (walking to the other side of the bed) - It is there! Look, it's on the floor!
Me - Well, I was wrong and you were right.
Ella - Why were you wrong?
Me - I can be wrong sometimes. Good, isn't it?
Ella (looking back at me from the doorway) - I'm never wrong.
Me - Yeah, I'd caught onto that.
