Well, I just tend to tell them to mind their own f business when it gets too much. Yes, I am sick of that preaching attitude as well. It might be a bit too much of an response for your particular situation, though - that is, if you need or want to be on a good standing with that friends of your wife. Me, I get so sick from that, that I simply don't care anymore, I ain't letting someone who doesn't even ride to preach me on how its done, I cut them off almost immediately.
