I had to go to one a few years back when I was in college. The one that I went to we did not have to talk or share. We were all in a big room and the ladies and family members stood up and told us about how their family was impacted by drunk drivers. It was very sad and very serious. I was not there because of a DUI, I had gotten another charge that was not related to driving. It was a difficult experience but one that I will never forget. Some may seem angry at you, but the best advice I can give you is just listen. Good luck!
