Adam and Brenda tell you that they want to do simple wills under which everything will pass to the survivor on the first death, until he or she dies or starts a new relationship. Whatever is left after that is to be used primarily to ensure that Charlotte has a roof over her head and adequate financial support while she is in full time education, but, subject to that, they want to ensure that all the children (and grandchildren if a child has predeceased) are treated fairly. They were going to draw the wills up themselves, and did some research on the internet which convinced them that mutual wills were the answer, but they sounded a bit complicated so they want you to draw them up and have made an appointment for that purpose.
Another of Hofstede's categories has to do with the way national cultures relate to uncertainty and ambiguity, and therefore, how well they may adapt to change. Generally, countries that show the most discomfort with ambiguity and uncertainty include Arab, Muslim, and traditional African countries, where high value is placed on conformity and safety, risk avoidance, and reliance on formal rules and rituals. Trust tends to be vested only in close family and friends. It may be difficult for outsider negotiators to establish relationships of confidence and trust with members of these national cultures.
