Friends and enemies--sometimes it's hard to tell the two apart. Especially when some people seem to be both. In her bestselling book Mean Girls , Hayley DiMarco counseled teens about how to handle mean girls at school or church who were making their lives miserable. But what's a girl to do when her own friends are the ones doing those mean and hurtful things--being her BFF one day but betraying her the next? Frenemies helps girls figure it out. In this new book from big-sister mentor Hayley DiMarco, teens will learn why friends act the way they do and how they should react when the mean people in their lives are the people they love and trust the most. Friends + Enemies = Frenemies Is your friend your BFF one day and your worst enemy the next? One day she's sweet and fun, and then WHAM! she's stabbing you in the back and spreading rumors about you. What gives? Maybe she's not outright cruel like a mean girl is. But because she's your friend she's got more dirt on you--and more opportunities to hurt you. You're not alone. Nearly everyone will be blindsided by a so-called friend at least once. But that doesn't make it any easier. If you're dealing with a frenemy (or several of them), you need to know when it's time to work through the relationship and when it's time to cut her loose and find some new friends.
