I thought about having W over to the house to discuss plans for D13 the rest of the way until school starts. Then at a pre-planned time, have someone (like Anna maybe) call the house, I'll tell the W "I'll just let it go to Voice Mail". Then after my outgoing message plays, the caller can start to leave a message (maybe in a sultry tone) like "Hi (DMF) this is XXXXX, I just wanted to call and thank you for..." Just then I pick up the phone and say, something like, "Hey, whats up?...Oh yeah?...Hey, can I call you back?, I'm in the middle of something...OK bye." Then make no reference to the call and look back at W and say, "Sorry, where were we?"
