That's what a patron told me yesterday. She proceeded to explain to my that she could see the vapors. She also said that in order for me to view them, I had to take pictures with the camera set on natural light exposure. This is when she pulled from her many backpacks, pictures of things like trees, the side of a house, and a toilet. All of the pictures had the glare of light.
I listened with grave difficulty. I was trying so hard not to laugh in that womans face. I just kept nodding and looking at her as if she had lost her mind. Thankyfully, she finally said, "OKAY, you have a good day now and walked away."
