Great topic
I remember a long time ago that a lady whom I had interviewed when we were recrutiing for an entry level position, told me that I was very intimidating. Later, when she got to know the "real me," she was totally dumfounded to find out I was funny, easy to talk to, understanding, etc.
I tend to keep my emotions well hidden until I know someone well. I would imagine she saw me as a Spock-type character at first. Me, I love healing and helping and I'm rather volatile, not to mention a romantic at heart. I see me as a Dr. McCoy. :-)
