I want to leave you with something to think about before your trip.
Another gem from these boards is from Ellie (aka KML). She speaks of using aikido, quote below from her in another thread:
"In Aikido, you use the force of the attacker himself to throw him off balance, by yielding and turning (or some such)."
In your case, Luke, you would want to use emotional aikido with W. When she's pushing hard for D, remove the resistance against D and work with her. It does not mean that YOU do all the leg work in D. Instead, tell W to send you the paperwork to get it started. The onus is on W to take care of D paperwork since she is the one who wants one.
You can tell W that D is not what you want, but you'd look at the paperwork when she sends it to you.
