I'm afraid Jake has a little obssessive/compulsive disorder in him. Several times I have found him gathering similar objects (cars, toy animals, minature shampoo/toothpaste containers) and lining them up in a row. He gets mad if they are messed up. Yesterday he came out of the bathroom carrying some items and this picture is what he did with them. My other two children did not do that. Anybody else have kids like that?
