What a night that turned in to! I think you did an excellent job teaching some life lessons at the conclusion of the disappointing night, while in the midst of all the emotions.

To go from the high positive to the low mix of emotions dealing with a drunk lady stiffing your family, and having the resolve to teach your D through it is commendable.
