Now that's odd. I always read Pratchett on the subway, in the large print hardcover version, occasionally waving it above my head and turning three hundred and sixty degrees while exclaiming: "I am reading Terry Pratchett! Pterry, over here!" on the off chance that I will meet a fellow fan, as I've only met one other person in real life who's ever read him*. I was Susan for Halloween. I live in NYC. Pterry had spoken there a week before to an audience of about five hundred. Not one person knew who I was.**


*Discounting signings and such.
**And my costume was obsessively good too.
