I took a fun test here and discovered this:

Are you a good friend?

Your score is: 65
Average is: 50

What does your score mean?
You rate a happy medium on the friendship scale. You are a regular good pal, someone friends can turn to turn to in times of need - whether emotional, financial, or otherwise. You are giving of your time and are generally thoughtful. While your heart is in the right place, however, you might sometimes slip up and forget special occasions or do slightly "selfish" things. This does not mean you are malicious or that you intend to hurt anyone - only that you are human. In fact, your approach to camaraderie is healthy and balanced; you realize that you don't always need to place your friends at the very top of your priority list, especially when it is to your own detriment. You know that true pals will respect, and even appreciate, your ability to say "no" or put yourself first from time to time. The most important thing is that you keep the lines of communication open and build the level of trust and respect necessary for a lasting bond.

I suppose it is true in a way. I will go to certain lengths for a friendship but if I'm not comfortable with something (say, endless borrowing of money or being an emotional vampire) I will not hesitate to distance myself from friends. As much as I value the bond between us, I will NOT be allowed to be used and to be abused. That is just not how friends should be. I would just want to be able to sleep peacefully at night with no worries about "friend problems". I've had my share of those and I realize, I don't want the unnecessary trouble (and wrinkles). For now, I am happy with positive and true people. Those are the people who will be a big influence on me and who can make me a better person.
