I've chosen to share this Loudon Wainwright song because he says much better than I ever could what love is between a brother and sister. He also distills in to one line the sweet longing of looking back at photos from childhood, when such things were more rare than today, as he sings "Whoever took that picture, why, they captured our whole world". I'm getting goosepimples just typing those words!

I have a brother who is seven years older than me but there are only fifteen months between my sister, who is the youngest, and me. This means that we pretty much grew up together, playing, fighting and sometimes being a comfort to each other. My sister has a much nicer spirit than me and as we've grown older she has been the glue that has kept us all together.

As with Loudon, there is a black and white picture from my own childhood taken of my sister and me. We are in a swimming pool on holiday. It is all in that picture - whoever took it (my Dad I expect) captured our whole world.
