I'm not sure about the nose ring
MARY...they don't bother me at all...heck if those things did there wouldn't be too many kids hanging around my house
...but I do know (although it is becoming less and less) some places have policies against facial jewelry. I would suggest if you don't always wear it...and wouldn't IF the job policies were against it...(my son couldn't wear his ear rings at the sporting goods store he worked at through high school and college) that you don't wear it to the interview. If it's ok then you can wear it after getting hired. Just my opinion....but what I really want to say is...
JUST BE YOURSELF MARY ~ YOU ARE AWESOME! THEY WOULD BE FOOLS TO NOT HIRE YOU!!
