We've been reading Shel Silverstein's Where the Sidewalk Ends, and Guthrie loved the poem about the child who uses his magic eraser to erase someone.
Just now, he came up to us in the kitchen, and said, "If my pencil that I bought had a magic eraser, I would use it to erase all of Turner's toys. Then he wouldn't have ANY toys to play with, and he would leave me alone."
I think the logic is faulty, but the sentiment is right.
Thank goodness there is no magic eraser, or brothers everywhere would instead erase each other.
