JL's beauty sleep

JL: mum, I didn't have my beauty sleep today.
Me: what? You didn't have what? (I was surprised to hear her using the words 'beauty sleep' cos I've never said that & neither has Damien, so I'm wondering where she picked that up from)
JL: beauty sleep
Me: what is beauty sleep? (I'm wondering if she knows the meaning of beauty sleep)
JL: it's when you go to sleep & wake up beautiful
Me: oh, okay... (well, close enough)
