Every year federal employees, military types in particular, receive Performance Appraisals. The format generally revolves around stating the criteria to be assessed in one column and then the supervisor offers their appraisal in a neighboring column.
One of my criteria is to edit and correct outgoing correspondence because, you know, all them college grads can't be trusted to write proper sentences and paragraphs.
So my review reads, "Snuggle Bunny is a subject matter expert on AR 25-50 and corrects all correspondence as he is supposed to."
"Is that OK?" my supervisor asks.
""No, sir."
"What? Why?"
"You ended your sentence with a preposition, sir."
