alone at the barbecue

Am I alone in the fact that all my friends and family tend to try and change the subject when i talk about the stock market , their eyes glaze over and suddenly every thing around them is so much more interesting than everything i am saying. Every time I am invited to a social gathering I seem to scan the room for a like minded soul but to no avail... The ones that truly love me can tolerate it for a little while.. but when you have no one to talk to but your kids and your ten year old knows more about rio tinto than her teacher it's time to ask are there any social gatherings out there for people like me .. can you give me a few leads to find someone to talk to?
