I don't like any boyish sounding names on girls, such as
Willie,
Tommie,
Frankie,
Johnnie etc. So it stands to reason I don't care for
Jo or
Joey, either. I'm not wild about any full name that
Jo or
Joey could be a nickname for, so at least it isn't a case of "I like the full name but wouldn't want her to be called...." as it is with
Veronica /
Ronnie.
