How well do you know__?

On Facebook there's this new app where you can find out "how well you know __?". Basically, you make yourself a quiz of roughly 15 questions that you invite your friends to take. I was shocked at the results; I usually got anywhere from 33%-85%, and these are some of my closest friends. One is even my sister, and I normally failed.
Now, I'll be the first to admit that some of the questions were things you would have never known, even if you were extremely close to the person. But others were things like How long have I lived here? What do I want to be when I'm older? What's my favorite color, animal, song? What is my animal's name? Honestly, I was ashamed at some of the questions I missed.
We should be wanting to find every little detail about each other, because -if we truly care about them- we are fascinated by our friends. We should want to know their strengths and weaknesses; their hopes and dreams; their successes and failures; their hurts and pains. Because if we truly care about them, we need to show it. It doesn't always have to be about me. It shouldn't always be me complaining. It shouldn't be me talking about my life. It shouldn't be me talking about my future and past. We can't be so selfish all the time! We have to love and care. We have to worry about our friends. We have to show them that we have interest in their lives; only then can strong friendships grow and develop.
