I also keep my mouth shut unless asked. I don't want to hear 45 minutes of crap about quilting, they probably don't want to hear 45 minutes about brewing. Though I was at a conference once and this dude kept asking questions. I tried to change the subject but he kept asking. I talked for over an hour. I tried to offer to buy the second pitcher, but he was too drunk for more and went to bed.The only person I recommend beers to is my wife. She is expanding her palate and trying new things and I know her well enough to be pretty successful most of the time. Plus, I she doesn't like it, I get to drink it. :-)
some people ask me what to order. some of them I know don't like really hoppy stuff so I just tell them which beers aren't really hoppy. others I know like strong and dark beers (old ale, etc.) and I recommend something along those lines. for the most part I agree I don't like to recommend beers.
