I have to pipe in. I have a very difficult time putting off discussions. If something's bothering me, it will eat away at me until I deal with it.
If I was on the receiving end of an email that said "We have something really serious to talk about, it's about __this__, but we can't say peep about it for three days" then I would spend three days worrying about what's going to happen at that meeting. I admit, I have mild anxiety and tend to worry more than I need to, but this approach would not work at all for me.
That being said, the fact that your husband and you agreed to this talk some time ago, it doesn't sound like you guys suffer from my disposition.
Gralson: my husband (works out of town).
Auto: my girlfriend (lives with her husband Zoffee).
The most dangerous phrase in the English language is "we've always done it this way."
