But, if you are an idealist like me, you should be alerted you're up for disappointment. People will fail (you). The world won't change (like you thought it would at your voice). Like I said before: here (right here) is a cold dark uncompromising world.
Then, in the midst of everything, the most unexpected of people will act in the most unexpected of ways (like in the ways the advertisements noted). Here is still a cold dark uncompromising world. But, it is to contrast the people that follow through- the humans with whom interactions have meaning.
