The Pathetic Fallacy, Pregnancy Edition

Today at work the ladies organized a "sprinkle" for a teacher who is very pregnant with her second child (and leaving at the end of the week) and it took me a couple hours to comprehend the term for the party . . . you have a baby "shower" for the first kid and then for the next kid, it's not as big a deal, so you tone the weather down a bit . . . and I guess for a third kid, you just get a "mist" or a "fog."
