But here we are, spending the afternoon together, and he's quite (extrovertly) adamant about it.

I spend the afternoon wallowing in the tub, feeling the aches of physical exertion melt away.

The scenery alone would have made the car journey an agreeable way to spend the afternoon.

He spent the afternoon with his buttonslide, Brasso and buffing cloths, and he could not have been smarter even on passing-out parade.

They spent the afternoon planning and teasing the sour counterman until his heavy middle shook with hard chuckles.
