The rest of them (dad's side) do - my parents moved us across the country when my brother and I were kids. The rest of the family hasn't left the fifty-mile radius they were born in. My mother's side (those still alive) are scattered around, though.
We live over 100 miles from any family and soon farther. We have to travel to them in order to see them. Grandparents are irrelevant to my life. It wouldn't matter if they fell off the face of the Earth because I refuse to care about those who don't care about me, and ones that care too much in that disgusting way!
