Like if you look at this interaction:
Dr. "Can you tell me the last five presidents?"
Me: "Of the United States?"

Did you really think he’d ask presidents of some other country and wouldn’t he then specify that?

Dr. "Yes."
Me: "Does last include current?"
Dr. "Excuse me?"
Me: "If you asked me what I've done the last five mornings, you probably wouldn't expect me to start with, 'I talked to you', you'd probably want me to start with the 'last' morning not including this one."

You could just list them including or not including, no matter. Example of what you did in the morning sounds a bit “smart pants” and sounds as you are criticizing style of questioning, you aren’t there for that

Dr. "Oh, sure. Yes, by inauguration."
Me: "Trump, Obama, Obama..."
Dr. "Okay, not by inauguration...last five individuals who were President of the United States, starting with the current one."...

It’s obvious Obama served twice but why repeat twice. Maybe you could repeat twice but mentioned Obama served twice. He asked for 5 presidents? You were going to list 4? But he didn’t ask for 4. Do you always answer like that? If I am asked last 5 people visiting my house, I wouldn’t list my mom twice. Or I’d specify “mom came here twice”.

Is that how you always answer questions? With a lot of clarification fixation questions or your own examples? Or just these type of questions?
