In fact, I understood that it was absolutely necessary to speak English because we only heard English in the halls. As Kelly said, when you speak French, people answer you in English. That isn't very easy. For example, if you're part of a group of people and you're only speaking French, you have to listen to what they say, but they don't speak French. It's hard to follow the conversation and to fit into the group.
Newcomers who speak French are often forced to group together. Integration therefore isn't so easy because they're always with each other, since they understand each other. There's no real contact with others. When we come here, we shouldn't remain amongst ourselves; we have to be able to do things, think like the people here and know the ideologies from here.
