As of Monday night, Art has said he would like to be a scientist when he grows up, so he can discover new dinosaur bones. This is only the second time in his long 4 1/2 years that he has volunteered a vocational desire. The last time was about two years ago, when he said he wanted to a Mama. I asked him again today if that was still how he felt and he said yes. He added, "Because my shovel is not really strong enough to dig the bones. It kind of bends."
