Flannery's interests

We'll start with the books I got from the library today - one on tractors, one on airplanes, 2 on squirrels and an assortment of Dr. Seuss books.
She's so in love with tractors and trucks that when we go for walks all she can say in her breathless admiration is "Mama! Look at all my trucks!"
A few weeks ago, we were at a stoplight and a tractor pulled up beside us. I pointed this out to Flannery but heard no response. I mentioned it again. Silence. I turned around to see why she was so quiet and saw my 2 year-old GIRL leaning as far towards the other window as her carseat straps would allow, mouth hanging open, speechless in her wonderment at the Caterpillar in the next lane.
