My "best friend" of almost 4 years now has always been competitive, but it's never been something we've discussed. Every time I'm wearing something trendy or saying something new, she will do the same thing. When we used to run in aerobics class, she would constantly try to beat my scores. I confronted her about that, but she never seems to learn — she still copies me and competes with everything from grades to guys. If I address the problems I've had in the past, I will look stupid because usually I would be the type to bring it up, but my life was too hectic at the time. Should I really "waste" time talking to her about her competitiveness? Or, is there a way to hint at it or persuade her to do something original?
