Life isn't theoritcal, it doesn't run on slogans and logical quotes. It always demands that you pick a side and stand there. That is why we take different paths because of the difference in our personalities, beliefs and thought patterns. When you don't make a choice, it makes one for you while you think you aren't choosing. You are unconsciously standing for something, just not bold about it and those on the outside always see it.
Even you personally get to see it, in your actions, your words but fail to admit it because what you want life to be and what it actually is don't match.
