When It Comes To Girls (and In Colin's Case, It So Often Did), Everyone Has A Type. Colin Singleton's Type Was Not Physical But Linguistic: He Liked Katherines. And Not Katies Or Kats Or Kitties Or Cathys Or Rynns Or Trinas Or Kays Or Kates Or, God Forbid, Catherines. K-a-t-h-e-r-i-n-e. He Had Dated 19 Girls. All Of Them Had Been Named Katherine. And All Of Them- Every Single Solitary One- Had Dumped Him.
