Yes, D even roomed with some of her friends at the private U that several of them attended and their group was one of the most inclusive in their HS. They had unwritten rules as well, such as for major events (like proms), one had to invite only guests that got along with EVERYONE male and female that was in their group, so that if the couple needed some breathing room, everyone could chat with everyone. It kept things much more comfortable for everyone.
D’s group was also into bringing food and sharing with everyone, so they had a lot of folks who liked to visit their group since visits were delicious. 
D is so pleased that she has what she believes will be lifelong friends after such a bumpy time as a pre-teen and young teen.
