My teachers and my friends call me Kitty in school, while my colleagues and my boss call me Kay in the office. My friends and my colleagues have called me different names, but I have never told them which I preferred.

Should I say this?
You can call me Kitty or Kay
And then in the full name row of the registration form, should I write "Kitty Kay
myFamilyName" or just "Kitty
