Flow of consciousness

What makes human relationships unique? It's expectations, that expectation from others and others to you. Human relationships is not built on logic, technology and should not be. It is that sense of security that you can only get from your family, your best friends, and your other half. It is that somebody whom makes you sleepless, it is the first person you call when you are in trouble and knowing that he/she will be there for you no matter what, it is the number you can always remember even without phone book, it is tons of troublesomeness and still enjoying it, it is that level of intimacy that makes everybody else envious. That is what makes human relationship beautiful and unique, right?
