BFFs: Lindsay Lohan and Paris Hiilton

Rule: Don't fall down the rabbit hole.

Sometimes friends can have a negative impact in your life. So when you see that your best friend is in trouble, the obvious thing would be to offer your help and support. But what happens if you're in the same kind of trouble? Paris just served her 22 days, and now her pal Lindsay is following suit. After spending over two months in rehab, Lindsay just completed her very short 84 minutes stint in jail. So what's the lesson here? If you're friend's in trouble, don't go down with her; instead, help her find her way back up.
