Grandma?

Before beginning the drive, Mitt Romney put Seamus, the family's
hulking Irish setter, in a dog carrier and attached it to the station
wagon's roof rack. He'd built a windshield for the carrier, to make the
ride more comfortable for the dog.

As the oldest son, Tagg Romney commandeered the way-back of the wagon,
keeping his eyes fixed out the rear window, where he glimpsed the first
sign of trouble. ''Dad!'' he yelled. ''Gross!'' A brown liquid was
dripping down the back window, payback from an Irish setter who'd been
riding on the roof in the wind for hours.

As the rest of the boys joined in the howls of disgust, Romney coolly
pulled off the highway and into a service station. There, he borrowed a
hose, washed down Seamus and the car, then hopped back onto the highway.
It was a tiny preview of a trait he would grow famous for in business:
emotion-free crisis management.
