I don't have much to talk about that would be of interest to anyone but another techie. and not just "any" techie; one of my specific ilk. Really obscure, boring sh!t to you mere mortals.

Yes, talking in great technical detail about the specifics of your job would be boring to anyone who doesn't do your job, including me. But who says you need to talk in great technical detail?

But W wants to talk about "my day". because...she's a girl, and thats what girls do.

Nope, that's not it at all. I talk to friends, my mother, your mother, etc. and I don't ask them about their day. I want to know about *your* day because you are my husband, my partner. I want to connect with you and the way that is most natural for me to do that is to talk with you. "With you" meaning an exchange of ideas, observations, concerns, etc. -- "conversation."

Usually, it only takes 10-15 seconds of me talking about "my day" before her eyeballs roll back into her head. But it still doesn't satisfy her need. she wants me to have something interesting to say...but I don't.

And this tells me that you have no idea what it is that I'm looking for when I want to know about your day, probably because I've never communicated it very well to you.

I don't want to know the nitty-gritty specifics of how you execute your job on a daily basis. I couldn't possibly understand it because I haven't your training and decade of experience. And I'm not really technically oriented. Trying to talk to me in specifics is indeed pointless. What I'm looking to find out how *you* are. How are you doing? I have to wait for you to break out with a cold sore to know that you're feeling stressed about something. You can tell me that you're concerned about a major upgrade or installation of new equipment without going into technicaly specifics and I can listen to your concerns and support you.
