We weren't rich enough to own a jet (Grisham) or a pro football team (Clancy), but by the standards of Derry, Maine, we were quite rolling in it. We made love thousands of times, saw thousands of movies, read thousands of books (Jo storing hers under her side of the bed at the end of the day, more often than not). And perhaps the greatest blessing was that we never knew how short the time was.
Question 1: What’s the meaning of ‘we were quite rolling in it?’
Question 2: we were quite rolling in it --- what does ‘it’ refer to? ( 'rich enough to own a plane like Grisham OR 'a pro football team like Clancy?' )
