Question: Article: During my first two weeks at the University of California , Berkeley , I experienced some unexpected , funny , and sometimes embarrassing situations . Allow me to share some with you . But first , let me give advice to other foreign students who plan to study in the United States . Check the weather before coming ! I was very sure that California was sunny all year around so I left all my jackets and sweaters in Paris . It was a huge mistake ! It rained almost every day during the first week in Berkeley . I have to say that I quickly forgot these unlucky events . Life in Berkeley is very pleasant and everything is so easy compared to Paris . For example , in only 24 hours I bought a mobile phone and made the lease agreement for a flat . What's more , almost all the shops are open on Sunday , which is very practical for me . The first thing that surprised me is that students may come late to class . They freely enter and leave the classroom many times during class , In France , students respect the teacher's lesson , so they are never late and they leave the classroom only at the end of the class . The local people in California are in general very nice , open and active , However , I am not totally used to their habits yet . Indeed , I was used to shaking my friends' hands every day in France . During my second day at Berkeley , I shook the hand of one of my classmates whom I had met the day before and he told me "I think we already met !" Another funny story happened during the first party I attended : A girl that I meet before came to hug me . I thought she wanted to kiss me like we usually do in France to say hello . So I kissed her and she seemed a little bit embarrassed . I live a great experience at present , and I would just encourage any student to become a member in a program at UC , Berkeley . Question: When the writer's classmate said "I think we already met !" , he meant _ . Yes or no, is the answer "Americans needn't shake hands when they met again"?

No
