Today at my Columbia alumni fiction group, I got probably the best comment ever on the first chapter of a novel I am working on:
"If your protagonist has a reason for the casual employment of Yiddish, it will need to be explained for the general reader."
You know you're a real New Yorker when casual Yiddish starts showing up in your recreational fiction projects.
En route to the meeting I noticed that on 113th Street someone had the sense to use a chain link fence around a parking lot as a trellis for roses. Oh, Columbia. You're so civilized.
