Blondie hit the nail on the head in her last sentence about those who are allergic at the kh, but apparently no other place! I had never heard of so many "allergies" as I heard of at the first kh I attended! Perfume, down, new carpet, chronic fatigue, you name it! There were a few public needs talks given on being sensitive to those with the allergies, and could people please refrain from wearing scents. I wore scented powder on occasion, and was in fs with a woman who had real (not really real, but real to her) scent allergies, and the woman who studied with me. Real allergy woman asked if I was wearing any scents, said she was allergic to my scent , was getting a headache, and couldn't go in fs with me. The other woman said she wondered if it was just her, that she had a splitting headache from my "scent" as well, and couldn't go out with me. The next day we were in fs in her van, I was in the back, and HER perfume, that I could smell all the way in the back, actually made me sick! I wasn't allergic, just hated the perfume. I said nothing. We all have several stories like that, I'm sure.
As leaving quietly said, there are those with real allergies, but I found those were the ones that rarely complained. I think the others just wanted attention.
