Murrow’s understanding more and more of what we say these days. We can tell him to close the refrigerator door, and he closes it. We can tell him to go get his water cup, and he brings it to us. We can tell him to give us kisses, and he leans in for one. When he’s getting into his jammies at night, he’ll remove his socks at our bidding, and toss them into the hamper. And when we ask him to show us his tongue, he gladly complies.
