I know a
Phyllis in her 80s and another who would have been in her 60s now.
I quite like it, though I prefer
Phyllida.
Phyllis can sound like the Afrikaans word for rubbish or garbage, but I don't think that's my problem - more likely the hissy -s ending. I don't enjoy
Denise,
Gladys or
Janice either.
