I wonder how far in the steps this so called sponsor has assisted you to reach, and I just have a feeling that's it's not very far. Please keep in mind that many people change sponsors, and if you see someone you think you can relate to better then ask her. Some sponsors would have had you finished with the steps at four months, some others still messing around and not even getting past 4 & 5, which is where very often the good feelings of this program start kicking in. I love so much about AA, but don't like the different qualities in people who sponsor, in one room we can find very good, medium good and hopeless, sorry to say but I believe yours falls in the last category.
This happened to me as well, more than one of them, every meeting I went to there they were. And there was me, nervous, bad coffee and hard chair, not enjoying these meetings at all, and these old timers loved to talk just like your example. Luckily there was one I saw who just came to one meeting each week, he said he comes to pass on what he learned when he was new. I spoke to him, and he said some folks like the clique of other old timers have not much else in life, and coming to meetings was an outing for them. So have no fear about that, meetings do become more 'fun' as as we go along, and when the steps are done you may go just to help others and see some friends, you won't have to go because of fear that you will start drinking if you don't.We have some old-timers here, one just celebrated 33 years of sobriety! And he still comes to meetings!
If you get the Joe & Charlie with writing on it that avaneesh spoke of, and follow along with your book, you will get a better understanding of the steps, no need to overdo just a little read when you feel like, if we go too fast it's hard to absorb. It's going to work out, keep the faith that AA works, and best of luck.
