I Wish I Had a Brother

I mean I have two sisters. I'm the middle child. One is 27 , I'm 21 and the other one will be 20 this month. I guess it's better than being an only child, but sometimes I really do wish I had a brother by blood. I mean I have guys in my life that I call my brothers and my cousins act as my over protective big brothers, but sometimes I wonder what it would have been like if I had a real brother.
