Every day when I go to pick up toys, I find the line up. The line up may be airplanes, trucks, cars or trains. The line up can be found in different places of the house, the kitchen, bedrooms, family room and even the bath tub. I find myself very amused every time. Neither Zach or myself are people that need to have things in precise order. Who knows what this little person is thinking, but he loves to make the line up.
