Arsenic

She was caramel coated but it could have easily been arsenic. She walked into a room, made balloon animals with your heart and just as easily walk away. 

It was one of those static walks where she was drifting across the room but her legs were not moving. She smiled just enough to show the satisfaction in her work but not enough to lose your interest. 

If she did lose your interest, it would easily be found again. She was an artist with a sharpened and filed paint brush with only one base color, red.
