Enjoy your time in Vegas. As for that woman on the plane and her "partner"...they sound like a pair made in heaven. Yuck! As you travel the path, you'll notice more and more of the people who are in crisis.
I'm glad your girls are staying w/family so that you can enjoy your trip. You know that they are well taken care of and will be happy upon your return. All of you will have lots to talk about.
Wishing you a safe journey.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
