I find it very hard to tell some of my brilliant friends that it appears that they are <i>in this case</i> talking our of their fundaments, or at least being somewhat nuts. I used to be more critical, but then people would not want to talk to me. So I learned to be constructive and positive. Which is a great thing and I thank California culture for that. However, I can't find a good way to be an ass to my friends for their own good. (assuing I'm not talking out of mine, of course)<p>Any tips anyone?
