I was at school with a
Candy.
Candy Mercia Anne, or perhaps
Marcia. The teachers never recovered: at the start of every year she faced the same interrogation - was she sure, was it really on her birth certificate, had she checked with her mother?
She was quite bright, quite pleasant, quite pretty and a good swimmer. Every summer her blonde hair turned green from the pool chemicals. Nobody quite liked to suggest that they were interacting with hair chemicals!
I don't know from
Iggy Pop songs, but I've known too many dogs named
Honey,
Candy,
Sweetie etc to take it seriously on a human. I'd use
Candida, but only as a mn;
Candace used to be on a list of possibles but I've gone off it since
Candice and Candiss started emerging.
