Reunion behavior tends to follow a predictable pattern. We connect with our closest friends from school and spend the majority of reunion weekends with the most familiar faces. Everyone else gets the awkward name tag stare down or, worse, a "Good to see you Steve," only to be reminded that Steve's name is actually Shaun. Many people skip law school reunions to avoid such awkwardness or because they don't have good friends who are attending.
I encourage you to approach the reunion experience differently. Law school reunions are absolute goldmines for making new connections. We only really know a fraction of our classmates and we have lost touch with a good many over the years. At the same time, we know it's important to have strong networks in place for current or future job searches, for business development or for trusted peer level advice.
