Here is the story of "when Jenna first met Dennis" which Jenna told at Dennis' birthday dinner last night.
Jenna met Dennis when she was working behind the counter at Posteritati, Sam Sarowitz' movie poster store in Nolita (North Little Italy). Dennis came in and inquired about a certain movie poster. Then he looked around at things in the store and left.
When she next met him, it was five years later. I was introducing her to him in my kitchen in Portland.
