When you're really close with someone, it's inevitable that you're going to fight every now and then. Since my bff [1] and I are more like sisters, I can easily say that it's the worst feeling in the world when we argue. Since we've been friends for almost 30 years, we have our tiffs down to a science so they're as quick and painless as possible. Girls will be girls so ladies, tell me, how many fights did you get in with your best friend in 2007? [2]
