Some great advice here....I say go for it! I wish I had have stepped out of my comfort zone many years ago....took me 'til I was 40 to do so (I am your quintessential weird loner
). Now I am 50, I am far braver, have made some good friends (a real mix of younger and older people) and life is much richer for it. A smile is a good way to start.....if you do decide to go...let us know how it goes.
