A moment from my life and day job. For exposition’s sake, Jim is my boss.
Jim: Just double-checking. “Who’s” is “who is” and “whose” is possessive, right?
Me: Yeah, that’s right.
Jim: That’s what I thought. Just thought I’d double-check with the Grammar Police.
Me: I’m not the Grammar Police. I’m more like a Grammar Enforcer. I’m Grammar Batman.
