I agree with trying it twice then stay or leave by what your gut tells you. I joined a group last December that has met at our local HS every Wednesday for 10+ years. The oldest member is 81 and I was the younster at 50ish; all welcomed me and since 3 other youngsters have joined. Search for a group that you feel confortable as your time is too valuable to spend with those that make you feel less than good.
