I have to get the crab at 10 a.m. Mrs. Cohn Zohn is making crab Sunday night because it’s Grant’s 25th birthday — I remember when he was running around the house in a Batman costume at age 2. Grant’s brother and wife and kids are coming over for the birthday party. So, I have an errand this morning. That kills time. But I keep thinking about tonight’s game, how the world will be a little different after the game, how we’ll know more than we know now. That tugs on me. After the crab, I’ll come home and shower and shave and pack my computer and read the papers again. But the game will tug on me. Grant and I are leaving home around 12:30 for Candlestick. We can’t afford to get mired in traffic. This is a very big game and it tugs on me.
