Dave walks into the lounge room to find Charli - having gone through the drawer with all of our electronic equipment including old mobile phones - with a mobile plastered to her ear, yammering away to someone.
Dave: Charli, what are you doing? (sternly as she isn't meant to go into that drawer)
Charli: (looks up in surprise, turns back to the phone and whispers...) I'll call you back. (throws the phone back in the drawer and turns back to Dave with a 'butter wouldn't melt in my mouth' look.
Dave (leaves the room in stitches).
She may as well just have been born 14 years old....
