Oops! Sorry ladeeeee. My children never wore nail varnish and young ladies who grow their nails too long are told to get them trimmed, if that helps.
I don't have a problem with earrings any age group. That's a matter of culture.
Children grow up too soon these days, peer pressure, media pressure etc etc
If you're not happy about it you are right to say how you feel or be given the opportunity to say how you feel about it then move on with your life.
