So, for the second time this week, I got an email from someone where they finished the missive with PS. They then followed it with PSS. PS means postscript. With additional PS's added, it is usually PPS (Post-postscript), adding more Ps the more post the postscript you go. PSS drives me crazy. Postscript script? Nuts.
I have read a couple of places where people have rationalized a definition of Post-sub-script, but that seems like it is reaching. The indefinable "they" then go on to say that the next PS would be PPPS, so I am not sure I buy it.
It is like fingernails on a chalkboard to me, like people who say/write Sister-in-laws instead of Sisters-in-law. But I learned long ago that you come across as condescending and pedantic by trying to correct people's grammar, so I keep my mouth shut even though my head is screaming "my barbaric YAWP!" Sometimes I even have to grit my teeth.
So, grammar pet peeves? In the one place you can share them without coming across as though you are correcting someone? Just randomly mentioning grammar that drives you crazy--not the people who use it. Sound off in the comments if you need to add your "barbaric YAWP!" My thanks to Mr. Whitman.
