Mary's new Prius! Very Cool!
But why did Rob go out, unprovoked and buy Mary a brand new Prius???

Is it because he is a great husband? Or Mary is a loving, deserving wife? Is Rob so environementally conscious that he insists on a hybrid car? It may be all of those. But, hmm, how much weight should be given to this factor?

Rob nearly had a heart attack when he found out that Mary had backed the van over one of his precious rhododendrons (which he is now attempting to heal with duct tape and string). Is it just a coincidence that the new car has a screen that displays the view out the back when the car is in reverse?
