M has been known to shout things out while driving down the street, not unlike one of her uncles...
In this case, she has been learning the 3 Little Pigs story at school. Whenever she sees a building made of bricks she calls out "Brick House!" all the way home. :) I can't help but to be reminded of the song by the Commodores.
This reminds me of her early words. In Chicago, while strolling through the city, she would yell out "Bus!", "Bike", "Train!" whenever she identified any of these. The walk up the lake shore was hilarious with all of the bicycle traffic.
