You are very lucky. My family is nowhere even close to being close, friend wise and geographically. There are 5 of us. ! in Mass, 1 in CT, one in New York, 1 in texas and another in California. The one in Cali isn't far enough away, as far as I'm concerned.
My husband and I actually bought a house two yards away from my childhood home, and my parents still live in it. It's cool, cause my dad will just wander over in the evenings, and sit for hours talking and drinking coffee.
I'd say that there is some family member at my house at least three nights a week, if not more.
I'm in the same boat. My sister and I haven't lived anywhere near each other in over fifteen years.
I wish I had a close relationship with her, but when we're together, we have a huge fight two days after we see each other. It's like clockwork.
I love her, but I guess there are too many "issues," relating to our parents, that we'll never be able to get past.
