I never really had close girlfriends growing up. I knew lots of people, but I wandered from group to group without ever fully being part of one. I missed out on some of those wonderful relationships that last a lifetime--the ones where friends get together regularly and are in each others weddings and together for every life milestone. Because I didn't ever have that core group of friends, I am able to mix and mingle with all types of people, so I wouldn't change anything.
Having said that, I love that Corinne has a core group of good friends who may well last a lifetime. I can see these girls meeting at the beach once a year or throwing baby showers for each other years from now. I hope they will continue to cherish each other and nurture their friendships.
