Andy Rooney has announced he is stepping down from regular appearances on CBS’s “60 Minutes.” I’m relieved. He seems a nice enough guy, but I was beyond tired of his curmudgeonly observations at the end of each week’s show. I hope before I do something similar, someone who loves me will take me gently by the arm and lead me to the door. It would be more respectful than letting me prattle on while everyone tries desperately to feign interest.
