I sent the letter yesterday, he gets back tomorrow. I think that while he is gone, I should not bring it up. I asked him in the letter if he would please take time to respond to the same questions I responded to while he was gone.
So it wouldn't be fair to ask for a response until he gets back. However, if he doesn't have a response for me after he gets back, I will have to say something. He has had time to go to dinner, time to hang out with his friend Barry, time to sleep (I know it is a necessity, but still, priorities), and has not had to worry about kids waking up in the night like they did last night (and both got in my bed!). So if he wanted to reply, I would think that sitting alone in a quiet hotel room would allow him the opportunity to gather his thoughts....
