None so deaf as those who will not get a clue.

On the way into a show, I saw a woman tell her eightish son to move forward when the crowd moved, and he didn't. She told him again, and he still didn't. Then she said, angrily, "Will you listen to me? Move!" and dragged the boy by his arm.

I suppose this doesn't sound too Hellparenty, so let me back up a moment. In the queue for the show, I saw this same woman fussing over her son, putting earplugs in his ears. I guess she was worried that the show would be too loud for him. And I guess that someone should tell his mother that earplugs will make it harder for him to hear her, too.
