Family: can't live with them, can't live without them

There are those who will consider the subject of this post weird. They will wonder why at a time of so much international news of importance this was all I could find to write about, but I can't help it. I have family in town for the weekend, my two favourite aunts (all 5 of my aunts are my favourites, well maybe that's stretching it 4 out of 5) and my 19 month old cousin. This should be a joyful time right? So why can I not get the tension out of my shoulders? What is it about the arrival of family that makes me want to justify every decision I have made in the last 3 years. Why do I constantly need to explain myself to them? How come they can make me feel like I am 6 years old as opposed to 26? Is that why I felt the need to move halfway across the world from them? I have as much self confidence as anyone I know, why does that all vanish when they appear?
Family reading this, don't take offence, I'm merely attempting to understand the machinations of my ever more bizarre brain! It's definitely not you...It's just me.
