I'd always assumed Beth and I would be friends forever. But then in middle of the eighth grade, the Goldbergs went through the World's Nastiest Divorce.Beth went a little nuts.I don't blame her. When her dad got involved with this twenty-one year old dental hygienist, Beth got involved with the junk food aisle at the grocery store. She carried processed snack cakes the way toddlers carry teddy bears. She gained, like, twenty pounds, but I didn't think it was a big deal. I figured she'd get back to her usual weight once the shock wore off.Unfortunately, I wasn't the only person who noticed. May 14 was 'Fun and Fit Day" at Surry Middle School, so the gym was full of booths set up by local health clubs and doctors and dentists and sports leagues, all trying to entice us to not end up as couch potatoes. That part was fine. What wasn't fine was when the whole school sat down to watch the eighth-grade cheerleaders' program on physical fitness.
