It wasn't until we were in High School, though, that the intimacy that Sis and I shared with each other expanded to include other people, as well – Up through the end of middle school, Sis and I both had the usual assortment of friends: there were the people that we were willing to hang out with at school, a smaller number of people where we were comfortable visiting each other's homes after school, and a much smaller number of people that we were close enough to that we'd spend the night with.

Through the vagaries of the educational system, the people in each category shifted dramatically when we made the transition from middle school to high school. For one reason or another, Sis and I both lost the kids that were "overnighters" -" most ended up going to a different high school, and a few moved away completely. That meant that for both of us, we ended up becoming better friends with some of the kids in the middle category while we were getting to know the people at the new school.

Something else that happened was that Sis and I didn't have any classes together, and had different lunch periods (the school had 2 because the number of kids was so much greater than the cafeteria capacity). We still had time to visit a little bit in the halls between classes, but that was about it.

On the plus side, because of how close we were with each other, we didn't feel the pressure that a lot of the other kids did to find a friend of the opposite gender to match up with. Of course, some of the new people that we met were thrown a bit by how well Sis and I got along, but when they learned that we were fraternal twins, that seemed to settle it for them. The friends we still had from middle school knew that we got along a lot better than most people would think, but not _how much_ better.
