A dear friend, a very expressive talented singer, was getting very touchy at a business party with a gentlemen (who was and is gay) who was very amused by her blatantly touching his chest pretending to be reading his name tag.
I said to her later that its fine that Jim was amused (maybe even flattered) by her touching him on his name tag, but that could cause trouble with the wrong person. She said "Well, I'm bipolar!" I said I never knew that, would never have known in general. She said, "Well, I'm not officially, but my sister is!"
