Wait a minute. What the? And this is how I replied:
"Didn't we have this conversation after church with her husband today? I heard him talking about how he'll be busy this fall, and that's the reason, blah, blah, blah. Remember, I turned to you and said, 'See, you were the one who guessed first, and you were right.' And then I turned to him and said, 'But we never ask. Congrats. We think it's great!'"
And then my husband replied, after nearly falling over with laughter:
"We were talking about how World of Warcraft 2 is going to be released in November. That's why he'll be so busy. I thought you were being awfully nice and unusually supportive about it."
It's too bad my foot fits so nicely in my mouth.
*BTW, she is pregnant, and she's having a boy in December. She said so herself. At least I know enough not to ask!
