Ngikik ngakak gila=Laughing for no reason

Yesterday i walked around school with my bestfriend. She is my best friend since i was in the kindergarten. Yeah, although she isn't at the same class with me. She is very funny, and i'm funny too. We usually walks around the school building with throwing funny joke. Sometimes we began to joke about ourselves, and joke about each other. Yesterday, i walked again with her. But, when i saw someone that i didn't want to see, i rotate my walk, but in the other side, there was a people whom always disturbing me, and i hate him. Then, i thought to rotate my way back. And i choose the first way. My best friend, laugh very loud and because i embarassed, i laugh like her. And try to avoid the people. After that, we continued to joke each other. What a crazy people we are. But our friendship is stronger than anyone in the world! Hope so.
