Family time.

Coming from a large and yet very isolated family means a lot things. Mostly that there is a group a people who are out there that you need to be aware of for a variety of reasons. First and foremost you don't want to be the person sitting at a large party and trying to figure out who you are and aren't related too. Seriously this happened to me twice. Needless to say after about the 3rd time you say how about that one. You just resign yourself to to be being related to everyone and just get drunk. You tend to learn to ask if this is a "family party" (and not family like my friends use the term but actual blood/marriage relations)  then be forward enough to ask who are the eligible victims.
Secondly being isolated from the major group means events like the one previously mentioned but also that you make create a new family/families.Some will call it building communities and what not but I really look at it as family you are responsible to them after yourself. I have been a lucky bastard in that respect because a lot of people around me share the same sentiment. It may be that we became isolated from the larger groups for any variety of reasons and here amongst each other we are finding the roles being played/filled by a group of people we never knew existed but always wanted and are now able to appreciate.  I write a ton of things mostly in reaction to events and stress.
