SURPRISEE

I want to make a confession. Began from secondary class in senior high school. In that time, there was answer of 'N' test. Actually, i didn't trust it. But my friends told me that it was really the answer. I asked them, how could? Then they told me that it was last year test. I trusted and I memorized very well. Damn! the answer was true. After that, I searched and I got new info. My friends was lie to me. But no problem, they might be close how they could get the answer. After that, I always searched the answer to next text until now. And what a wonderful day!! Yesterday, in my habit i only memorized the answer and I didn't know why I didn't print the question. After finished physics exam, i think that it would over. And do you know what happened next? 'N' had different answer from the answer that I memorized because It was different question!! Surprise! I didn't know anything really :"(
