ISFP + ISFJ

These two have enough similarities to form a strong connection and enough differences to create that spark. In time, they may learn that they are both fascinating and soothing to one another.

ISF(J)'s are conservative in nature, choosing to go by established ways, while the ISF(P) desires to just be in the here and now, not planning nor preparing-just going for whatever action excites them and not waiting for anyone.

The J and P differences (in any coupling) tend to be the greatest point of contention.  If there isn't a balance or effort to grow and bridge the gap between these dichotomies, then J's end up feeling resentment for handling all of the details while P's feel bogged down by schedules and predictability.
