Same here, Edge - I'm going to choose "Sibling". I am very close with my sister still, she lives just one town away about 10 mins from here. I have kind of fallen out of touch with my brother because he lives farther away (about 2 hours), but recently we started talking again when The Elder Scrolls IV: Oblivion was re-released two weeks ago. It was just like old times, as we poured thousands of hours into that game. He might be coming up to visit this weekend so that will give us a chance to talk some more. I'll be honest - I have no one to blame but myself for letting us get sort of "estranged". He moved away right at the time that I got married and life got busy. But growing up he was my best friend until I was in my 20's!
Have a great day!
