I perfected a kind of beatific, Mother-Mary smile to beam at them, like I was trying to remember exactly what sex with God had been like, a bit distracted from the pedestrian world and its nominations.  The kind of smile that is holy-but-weird enough that the original question gets deflected.  So that when I said eventually, "We don't have one yet, for a boy, if it's a boy...." it didn't even sound all that bad or bothersome.
