If I know someone is over sensitive on a subject I'll leave it alone, however I have put my foot in my mouth a lot in my life. In fact one time a girl I worked with said she was going on a date, I said who was the lucky guy when it dawned on me seconds latter that she was a lesbian. She just laughed, and she is now married to that girl and I went to the wedding but it was still a ahhh sorry moment.
