Humans.
Among all the living species in this earth, I believe that they are the hardest to live with and the hardest kind to figure out. We may say that science would help us figure humans out but that isn't enough. I can't really identify who people are or what they really want. Figuring out who they are. People are too spontaneous. The baggage that comes with them fails to inform us of how heavy the load they carry or if they carry any load at all.
We practically spend a lifetime either trying to live with them or just being fed up with them and we just suddenly die. No one has a definite answer to who they are. Maybe that's why in relationship stat's in social networks there's a "IT'S COMPLICATED" button to choose from.
Isn't that the best definition for who are "COMPLICATED". Always have been. Always will be. I know that humans are special. But what makes them special?. Is it their bipolar ways?. Their constant love of all things lively?. The range of differences that complete them?. Or maybe there really is something inside of them that makes them so special.
