Lily: (with a donut in her hand) Did you know I'm not three feet tall yet?
Mommy: Actually, you 39 and 1/2 inches. So you are taller than three feet by three and 1/2 inches.
Lily: *thinks* Does that mean I can have
two donuts?!?
Update: (after leaving the donuts unattended for a shower-length time period)
Daddy: so, Lily, what do you want for lunch?
Lily: (standing with hands hidden in the doorway) nothing.
Daddy: surely you want SOMETHING for lunch.
Lily: (produces nibbled donut in right hand) I'm eating donuts. (Produces left hand) Here is the empty box.
(Small consolation: there were only two donuts left in the box)
