In FIP, we use a kinship system. There are about three upperclass leaders to every ten FIPers, and we call these groups "families." We mean that pretty literally; FIP families are all about care, nurturing, support, and connection, and your FIP "parents" are going to be looking out for you (even after FIP is over!). During FIP, you will do a lot of activities with your family and throughout everything your FIP parents will be your rock. The other leaders will be just as open to helping and supporting you, but of course they will have their own families.
As you might have guessed, FIP leaders/parents were FIPers themselves not long ago, and eventually you'll also have the chance to apply to be a leader if you so choose.
