My daughters are currently racing through Kathryn Lasky's Guardians of Ga'Hoole series. For some reason, their preferred reading position is sitting the wrong way around atop the back of the couch, with their legs dangling. When their father commented that this didn't look like a very practical way to sit, my seven-year-old - who is ever the jokester - turned her eyes skyward, started tapping a finger on her chin and sighed, "I wonder what practical means..."
Recently, the elastic on this girl's pyjama pants gave out. I offered to fix them, but she politely declined. You see, it suits a jokester's sensibilities to wear pants that will suddenly, inadvertently and routinely fall down.
