"WHERE'D YOU GO, BERNADETTE." By Maria Semple. Little, Brown. $25.99.Bernadette has a problem -- well, actually, she has a few. She is entirely exasperated by the way the streets are laid out in Seattle. She dislikes Canadians. She's not interested in helping out at her daughter's school, which values parental involvement and "global connectitude." She can be vocal, inclined toward sharing her opinions with her adolescent daughter Bee and brilliant, patient husband. Her opinions -- they are the problem. In one context, they are funny riffs; taken out of context, they can look like rants. And maybe a little insane.
