"You know that he won't visit if you're awake" Dad explained.
Liam persisted because he wanted to see Santa fill the stocking hanging on his door handle, but eventually he agreed to sleep.

"Told you he only comes when you're sleeping" Dad said.
"Ah, but I just closed my eyes and pretended to be sleeping" said Liam with a well-informed smile
