Thursday's interaction with CEO....

I was really busy as I had a patent filing deadline coming up- they're non-extendable.
CEO: Can you send me that information?
Me: Yes. Just doing the patent. Will do it after that.
CEO: Don't do the patent. Do (bit of work he wanted done)
Me: The patent has to go in by 3pm. I'll do it after lunch.
(20 minutes pass)
CEO: Are you in a mood?
Me: No, I'm having lunch.
CEO: You seem in a mood...
Me: No, I'm really having lunch.
CEO: Call me when you're back in the office
Me: OK

I go back to the office and do the final bits for my patent. Then I call him

CEO: What's wrong with you?
Me: Nothing, I'm just pretty busy and I was hungry so I went to get lunch.
CEO: No, it's not that. I know you and you're not happy
Me: No... I'm just busy
CEO: I'm not stupid you know. There's something wrong. What is it?
Me: Nothing- I've got a lot to get through today.
CEO: But I know you and I can tell when you're not happy. I know you.
Me: (dumbfounded and can't think of anything to say)
CEO: See, you ARE unhappy, and you called from my office. What's wrong?
Me: Nothing! Seriously, I'm just busy getting this stuff done and your office is easier to make calls from.
CEO: Is it because I'm not there?
Me: No, I'm just busy
CEO: Did you go to lunch with some man who told you you're wasting your life with me?
Me: No... I went by myself. And why do you assume another man would tell me I'm wasted with you?
CEO: Huh?
Me: (I was really getting annoyed) I don't know why you'd assume another man would say such a thing to me....
CEO: Well what is it? You're being quiet and I know you. You don't like that I've left you alone.
Me: No, seriously, I'm busy and I have to leave on time to get to dinner tonight
CEO: Is it because I told you to go to the dinner?
Me: no. I don't do things just because you tell me to you know. I do have a mind of my own.
CEO: (laughs) So you didn't go for lunch with anyone?
Me: (laugh) No. I was all alone. Now stop your nonsense and let me finish- I'm working very hard for you.

Then everything was fine and yesterday we exchanged probably 30 e-mails during the day having a normal bantering conversation about the dinner and other things.
