Today I feel a little bit dizzy. Actually it is start from yesterday. I don't know why. Yesterday-yesterday (what should we called in English I don't know) I was known all the level one student has go to the camp of jati diri. Then yesterday My friend told me that my father are blame to the teachers back for that. That is actually my father has know it at Friday. I have nothing to say but I want to share how to get the value of golden ratio.
