"I'd ask you to say hi to [name] for me, but you won't."
"Sure, I'll say to [name] for you if you want."
"Say hi to [name] for me."
"Of course, that means that you'll then be taken up as a topic of conversation. I mean, that's what 'say hi for me' really ends up meaning: topicalize me. So, would you like to be a topic of conversation between [name] and me?"
"Okay, I think I'd prefer you not say hi to [name] for me."
Meanwhile: My father turns 73 today. My father worked thirty years in a meatpacking plant and then retired (at least, from that job). It's amazing to think that was more than twenty years ago.
