Usage examples of "busy-ness".
I remember that my mind, adrift and afloat amid our busy-ness, went all the way back to Biscayne Bay, to the time when I was toting her back to Daddy, when she sat huddled and miserable on the bow deck of the Busted Flush and I had felt a wistful lust when I looked at the shape of the lass in her white shorts.
The time I spent in the kitchen, slicing pound cake, dishing up mints, setting out coffee service, cream and sugar, transferring coffee from the kitchen-range coffee-pot into a silver `company' serving-pot - this busy-ness gave me time to pull myself together, not expose my own rut and (I hoped) cover some of my body odour simply by the odours of food and the fact that female clothing in those days was all-encompassing.
