1. They hated each other. When they met for the first time, Sally gave him ride to New York but they were incompatible and therefore they always had quarrels.
2. Harry said that girls and boys can't be just friends, and boys want to have sex with girls who they find attractive. On the other hand, Sally disagreed with this idea. I also disagree with Hally's idea. They can be just friends. I think so! I have lots of makes friends and they are just friends.
3. After they made a mistake, they didn't talk in a while. While they did not spend together, they realized their feelings to each other. Finally, Hally came to new year's party and told his feeling. Although they spent much time together, they were just friends at first. As they spent, they realized their affection to each other. It took so long time to realize it.
4. I really really love this movie. It's sometimes comedy but romantic. I will watch this movie again someday!
