I feel very sorry for their entire family regarding the divorce.  Even though the daughters are now adults that doesn't mean they aren't negatively affected.  Twenty-seven years is a long time to be married, and I think this translates to a long period of healing for the parents.  Its not a good situation.  I also wonder about the impact of the divorce on the daughters' image of the security of marriage for their own lives.  It seems that the parents did try for a long time.  I wish them well.
