re “I’d love to get lunch at that time as long as I don’t have something else going on,” or “I’ll plan on being there unless something changes.” Reminds me of the best insult I ever received. "I'll give you a call when I'm not busy". I never got a call. Ever. Still saw person around. No call. So of course, I keep that in my pocket to use in the future, after all, I'm busy too, I have paint to watch dry.
