You like her the way that she is right now and that's sweet... I'm sure a lot of people would be thrilled to hear that because it means you don't want to change them... but if the do make a change will you still like her? Maybe you'll like the new and improved version... if she makes a change it's something she's doing for her.. it might be a midlife thing - it might be she's bored with her current look - it might be that she just wants something different... (they wouldn't have hair colors in 1000s of shades if they didn't expect people to use them
Change isn't always bad.. (though fake bacon is bad... always..)
