The real answer is :

"Do we now? So you can say how shit I am at everything and how great you are? No, let's talk about how hard I'm working and how much of a responsibility it is to be the hunter gatherer for this family. Why do I never "need to talk?".

The smart answer is :

"Ok, let's do it tonight at 9. Oh, that clashes with your TV schedule does it? I'm sorry that I get in the way. I'm afraid that's the only slot I have - I'm busy talking shite on the internet at 9/I'm busy on an online conference chat at that time."

A smarter answer is :

"Ok, let's talk. We need to get our shit together don't we. I've not been 100% lately so sorry if I've not been as attentive as I should but I'm just a bit low right now. No, I'm not sure why but I'll be ok as long as you carry on being supportive."

See, that shit will make 'em feel guilty. We know that you've just been too busy chatting birds up on MSN and mopping up on Counter Strike but she don't know that shit. So just be nice about it - tell her she's great and you're shit - works every time.
