The only exposure I've ever had to Mark Kay was back when I used to live next to an older lady who sold it. In fact, I met her the day we moved in, because as I was carrying box after box of my possessions up three flights of stairs, she suddenly materialized out of thin air with a packet of Mary Kay brochures in her hand and a smile on her face. She was probably wanting to sell me some of this, but when I told her no girls were moving in with me, her face instantly turned grim and I never saw her again. Seriously, never again. It's like she vanished. In fact, I sometimes wonder if she even existed and if this isn't just a figment of my imagination.
Thanks Kinkan for making me remember that weird encounter!
