My Sister and The Hungry Dog

Borrowed from Cristin Carole via Facebook.
I'm 13, Cristin is 21.  She often took me to bars for photo booth snapshots.

I have three sisters that span two families and two generations.  My oldest sister could easily be the mother of my youngest sister.  In fact I could also be the mother of my youngest sister.  My oldest sister is not related in any way to my two younger sisters; people may call my sisters half-sisters.  But that makes no sense to me at all.  They are my sisters, through and through, wholly.
