its a combination of not being home with my siblings throughout their whole upbringing, and location. I'm the second oldest of 12, I haven't been in contact with some of my brothers/sisters for years. I have a brother who I haven't talked to since 2004, he hates me for some perceived slights when we were younger, I mean...real young, like 5-9yrs old, stupid shit like "well you got that toy, or this, and I didn't" type of gripes. It makes no sense to me. I always send him xmas/bday cards, I haven't heard from him since Xmas of 04.
I have another brother who I haven't seen, nor talked with since 2005. I have no idea why he doesn't like me, I also send xmas/bday cards, get no feedback whatsover. Damn, in short, all of my brothers/sisters are haven't heard from or talked too in years....I try to stay connected via FaceBook, I send xmas/bday cards...but zero feedback.
I think the reason for some of it is the fact that I was so much older than them. By the time I was out of the house, most of my brothers and sisters were younger than ten. So when they were growing up, going to school, dealing with things I was never there because I moved out and tried finding my place in the world. Most of my siblings prefer to live with mom/dad, and a side note, all of us are out of HS, yet only two of us are living outside of home, and only one of us is living outside of town/state, that sibling being me.
On the other hand, I do talk with my parents on a weekly basis, and we get along a lot better than the years of my upbringing...of any of my family members, I have the most issue with my mother(meaning most drama in my younger days), yet I talk to her almost daily and get along with her rather well.
