Family Ties

Just thinking about family tonight. Why are some people closer to use than our own blood family? There are some family that I haven't seen in a very long time & yet I see other people more often. I am going on a trip to see someone I've never met but I still don't see family as much. Do we take for granted that family will always be there? Do we think that they have to love us because we are family? Or not? But I do love my family even if they are a little disfunctional. And not because I have to, it's because I want to.
