More imagination:

This week Graham has made new friends in the house: a flashlight, a water bottle, and a sunglasses case (which he calls Mama). He talks to them, comforts them when they are hurt, and feeds them dinner.

I guess those people who claim kids can do without toys are right. He also, however, continues to love his train set. He can put the tracks together now, and doesn't really liked to be bothered while in the middle of the project.
