I tried to think about xmodem, ymodem, zmodem -- data transfer protocols lined up on a menu waiting for my choice like equally alluring varieties of beer chalked up on a blackboard menu _____in a wood paneled bar overlooking the Potomac. But all I could think of was _____the taste of German white wine in green glasses on the table between us in that schloss that overlooked the Rhine River. Our feet were touching lightly under the table.
