I'm supposed to be asleep!

This morning Mummy and Daddy took me to Grandma and Grandad's house.
Mummy and Daddy had sausage butties and I did lots of walking around holding Grandma's hands.
We stayed for tea and Grandma got me ready for bed before we left.
I was very quiet in the car on the way home so Mummy and Daddy thought I'd gone to sleep..
But nope!
