I assume she was trying to figure out what you have been doing with your time these last few weeks. And that she tought you would just slip up and tell her now.
Anyway why does it matter now if she knows? I may have miss this but does it really matter?
Glad you are still being fabulous. Think about the great time you and your D are going to have tomorrow and forget about her.
Oh and are you still out of beer or did you get a fresh shippment I need some for this weekend.
