Daddy's home! How was your day?

I've learned over about 8 years of marriage that this phrase means very different things to men and women. Or at least to Chris and me. The conversation generally goes something like this:

Chris: Daddy's home! How was your day?
Kevin: Fine.
Chris: What happened?
Kevin: Nothing.
Chris: Nothing happened?
Kevin: We went to lunch and I sent some email and talked to Rich.
Chris: Well, what about Pete, Jeremy, Robert and Dan?
Kevin: They're good.
Chris: Did you talk to them?
Kevin: Yes.
Chris: What did you talk about?
Kevin: Nothing much.
Chris: Did you talk to Pete?
Kevin: Yes.

.... and on and on... until later...

Kevin (on phone): Hey Dan, how are you?
Dan: Good.
Kevin: So I can't believe you got a bonus check today for being awesome!
Chris: What? Dan got a bonus check?
Kevin: Yes, he got it today for being awesome.
Chris: Well why didn't you TELL me that? That's important!

So my point is that when Chris asks me about my day, I give her the answer. Short, overall, in a neat little package. "Fine." So she probes and probes. And it turns out she wants details! This happens all the time, yet I've never been able to get it through my thick head. Sometimes I even think I'm giving details, but I'm not.

Am I alone, or is this a guy thing?
