My dinner was so funny...We talked about one class which professor always pick up students who don't concentrate to the class to answer questions. Pap told us that he has a trick. His trick is that you just pretend that you understand her, though you really don't know what the hell she's talking about. Eye contact is a very good manner if you wanna know. He said that he sat in the middle between P'Ning and Jum. Once the professor looked at him, he just looked into her eyes pretending that he really understood what she said so that she skipped to call him. P'Ning is the next victim. She's about to call but P'Ning was so quick. She nodded to the professor pretending that she understood whatever the professor said. Jum was too slow. She was so tired. Poor her because finally professor got her as the victim... hahaha...so ending that no one actually understood what she taught and had to pretend like this throughout the class :D ... Well, I believe that they understand all she said, it was just a joke... :)
