photogenic: its similar to working with Jews of the opposite gender. dont share personal stories or feelings, dont discuss your issues with them. I used to work in a large Jewish office with both women and men. a few of the men would come in and start conversations with the women, myself included.
One of the women always shared personal stories and had private jokes with one of the married men. He was married and she was not. Even though it was only 9-5, my point is that 9-5 is a long time.
bottom line, the less personal you are, the better.
