Best Friend-Best Friend: What a pair! While you border on being sickeningly close, you're always there for each other. Your mutual respect and trust makes your friendship one to emulate. Your closeness allows you both to relax together, be yourselves and understand that you'll be accepted and loved no matter what. What could be better? Be careful, though, because your demanding expectations of each other are unrealistic. While you both may be meeting them now, the slightest falloff on either of your parts will put your friendship in jeopardy. If that time comes, try to be forgiving: You two have a lot to offer each other.
Best Friend-Close Friend: Close may be the best thing that ever happened to Best Friend -- if Close can show Best Friend how to be tight without being so intense. If Best Friend's expectations can't be knocked down a notch or two, though, Close is sure to disappointment Best Friend, even if she doesn't mean to. If the two of you can learn to see eye to eye when it comes to friendship expectations, you'll be friends for a long time to come.
Best Friend-Casual Friend: Not the most compatible pair, Best Friend and Casual have different ideas about friendship. For this friendship to work, Best Friend must accept that Casual will not fulfill all of her needs, a hard thing for Best Friend to swallow. And Casual must figure out a way to cope with the fact that she'll be letting down Best Friend, even if she doesn't mean to. While Best Friend will benefit from recognizing that not all friends need to be joined at the hip for the relationship to be beneficial and enjoyable, her high expectations will no doubt lead to disappointment and frustration and possibly the end of the friendship.
Best Friend-Acquaintance: This pairing is too much of a strain on both parties. Your ideas about what it takes to be friends are at opposite ends of the spectrum, and finding a middle ground is unlikely. If you decide to stick together, Acquaintance had better get used to saying the words "I'm sorry" -- she'll be uttering them often when Best Friend's high friendship expectations go unmet. Don't feel badly when this friendship fizzles; not all friendships are beneficial or worth maintaining.
