The degree of friction and cooperation/agreement can greatly vary here. If person A has Sun in Cancer and person B has Moon in Sagittarius, the Sun person will feel like the Saggo moon just wants to party and is not responding appropriately. The party hungry Saggo Moon will demand a greater space for exploration and will feel tied down. Depending on the overall chart, the demands of each of both sides for greater flexibility may or may not be met. So what signs are we taling here, it makes a huge difference.
quincunx are not usually ‘that’ problematic but just require ‘adjustments’ so sun person may not always understand the moon signs emotional nature and vice versa.

Sun Quincunx Moon “Your perceptions of others and of life circumstances alter as you get older. As others misunderstand your intentions and you misjudge others' motivations, natural corrections occur for you. It is through concentrating on the core values of communication in relationships that you make major adjustments between your ego drives and your emotional needs. This becomes a critical mechanism for personal growth and development.” http://www.cafeastrology.com/natal/quincunxinterpretations.html
“your ties to the past and to emotional security are misaligned with the ways in which you consciously express your will and desire. The resulting stress is usually seen in relationships. In your desire to hold on to old friends and associates, you make enormous ¬concessions that interfere with your own development. You create situations that bind you with obligations to people and that are difficult to free yourself from. You so complicate your life this way that one would suspect your enjoy suffering at the hands of others.” From the book ‘Aspects and Personality’ by Karen Hamaker-Zondag
