So, I’m changing my posting name to my latest, and what will probably end up being most durable, nickname. “Kal” is becoming quite popular in my work and social life. Normally I reject or avoid nicknames because they can lead to unnecessary informality. I never found “Kikou,” “Ninou,” or “Kha” (some nicknames for Khalid and Nouredine) fitting or desirable. “Kal” is fine, and I don’t mind institutionalizing it. Kal does not rhyme with “call”; it’s Kal as in Kal Penn, but not in imitation.
