Where: Green/yellow line, D.C. metro
Who was reading: A youngish man with shortish hair and a lollipopish thing in his mouth (a lollipop). He had a tiny backpack that didn't look like it could even accommodate the tome in his hand.
How far along was he? His place was marked with an index finger, and it looked like he'd read a very respectable 500 pages or so.
But did he have a second finger marking his place in the endnotes? No. So maybe the whole thing was an elaborate fraud.
Is that book really worth it? Dude, I don't know. Lollipop Kid made it 450 pages past my best effort. I will say that Brief Interviews With Hideous Men and A Supposedly Fun Thing I'll Never Do Again are two of the best short-story and essay collections, respectively, I've ever read.
