Think about it: "Behind the eight-ball." What's it mean?
A few days ago I was riding my bike down Central Avenue, into the wind (which was considerably irritating.) I was on a long sidewalk/bike path on the right side of the road. As I pushed along, I realized there was something coming toward me, at a rapid clip; rolling along in the gutter. Something good-sized, about two feet in diameter. And as it passed me on the left, I realized it was...a large, inflatable Eight-Ball. The black ball with the white circle, and the 8. And I thought to myself, okay, what the hell does that mean?
And if it passes me going the opposite direction, am I behind it? Or in front of it?
