We are a mass of complications. We have souls that are maleable, which changes characteristics according to what we see and like. When we see a person who is everything we want to be ourselves, we emulate the person. When we see a person who stands out, but in a very sophisticated way, we try to figure out what makes the person tick, and extract a little of her sophistication for our own use. When our friends manage to get the things they want, we question, how come she gets it? I want it too. If I try and be like her, I'll probably succeed as well. So that's why they say that you bring a little part of your frens with you in each passing day. You pick and take characteristics from people whom you've crossed paths with and make it your own. You change a little of your thinking everytime someone shares with you their thoughts and feelings. You argue your point across as well, since you don't want to be seen as someone who just absorbs like a sponge and has no opinions. But neverthless, the other person will always affect you more than you think she/he would. You would stick to your point of view vehemently. But you know deep down, she'he has a point. What makes you the person that you are, will remain, in essence. But we're a mass of complications, because we have maleable souls.
