When you come to a meeting for the first time, you can expect to meet many nice people who will happily welcome you. Let them know this is your first meeting and they will happily help you get started. When the meeting starts, everyone will introduce themselves and there will be some readings and announcements.  Being new, a small group will take you into a side room and have a "First Step" meeting with you to explain the AA program in more detail and share with you a bit about when they joined the program.  You will be free to ask questions and share, but you are not required to.
