I was once telling a past pdoc about the kind of r/s I was looking for (and basically why he should marry me!). I felt the person would need psychological insight and awareness and depth of understanding so we wouldn't have stupid fights that could be easily explained away by some psychological jargon - a perfect world, right? I finished my speech with, "So, you see, I NEED a psychiatrist!" He replied, "Lucky you are here then! Let's continue."
