The good wife offers to change her day's plan to take her husband's car into the shop, get all the necessary services done, go the extra mile and fix something that's broken and get it under warranty.
The bad wife wrecks her husband's car in the afternoon on the way to pick up the kids, thereby saddling her family with hundreds of dollars in expenses, the aggravation of needing a rental, and not to mention higher insurance premiums.
The good husband takes this all in stride very graciously despite his wife's hellacious (sp?) maiming of his favorite material possession. Never a dull moment!
