I moved back to my hometown in 2012. I reconnected with an old friend. We became best friends. She talked to me about having MCS.
I became aware of it, informed and stopped wearing fragrances of all kinds, stopped using any product with any scent.
I began to advocate to independent local businesses on her behalf. We changed their use of various products that created a constant stream of stink. It allowed her to become more social. We developed a small community of people who also took care of their use of fragrances in order to spend time with her.
