What is make difference between human and robot?

Everyday I walk through in the crowd. I see many things that make sense about robot from my eyes. Such as; Their eyes have no shine, no dream, no hope,no bright and even feeling . These make me sad and bore. In fact, I believe that our eyes can project out our spirit and dream but why I can not see these from these people so I start to think about this. What kind of things or factors that make human different from robot? I listed them out which are:
Thinking system : Robots can not think with flexibility or we called creative thinking because robots can think only the data that they have installed and they can not think by themselves. This make me laugh with tear because there are many people who like this. That we can see in Thammakai temple where people believe in data that Thammakai’s monks have told them and they did themselves without elaborate thinking and we can see in our current priminister because he has no brain and made himself to be norminee for last priminister. Is it make sense?
Dream : Robots have no dream (may be they have but they can not express their dream or need so I imply that they do not have dream). I saw many people who have dream, Their eyes will full with shiny and bright spark. For example; My friend, His name is Tanaporn. His eyes always show his ambition to make his dream come true.
Movement : Robots’ movement will be the same way and direction. They have no different like I see at Klongsan pier. They manage people to walk in the same way with obstacles like animal and this picture brings me into my concious with ambiguity. I know that they want to make it easy for themselves to manage but more system is more robots like!! Another term of movement, Robots have no flexibility of thier own body like I have been see every days at Silom road. People always moving by their body with flexibility but in the same style and there have no difference in posture or action.
Feeling : Robots have no feeling like human nowaday because their face have no feeling. Although some people face are full with stress or depress but these show that we have feeling. However, I can not see any response from their face. Are they robots? or I assumed it myself? That is why I think arts are kinds of things that show about feeling which make human different from robot.
In conclusion, all of above factors are things that can change robot to be a man. However, I heard a sentence that help me to understand human’s sake. It is “Music is life” because music has rhytm (like our lifes have period of good time and bad time), melodies (like ways in our life that we choose them by ourselves),ending (like death) and feeling (like us who have smile,hurt,sad,joy, relax,angry,annoy,hungry and happy) so music is life and life is music.
