Lukasz (coming out of his room after bedtime): Mommy can I sleep in your bed?
Lukasz: Because that earthquake book - we only read a bit of it, but I'm scared of if there was an earthquake.
Me: Oh... So why do you want to sleep in my bed?
Lukasz - Pecause (a Lukasz word) I don't a-usually (another Lukasz word) have bad dreams in your bed.
Good enough reason for me!
