Discussion in the lounge room:
Miss 8: "Is this a foot (indicating her foot) or is this a foot (indicating a span of distance)?"
Me: "Very good, a foot can either be a physical thing or a unit of measure."
Miss 8: "I know, but it's not an Australian unit of measurement."
Me: (to hubby) "Were we this smart at that age?"
Miss 10: "Nope!"
