M: Hey, Jenny, what's the matter? ,F: I was just online in a chat room with three Germans. They used a lot of idioms on purpose and I didn't understand, so I asked them what they meant. Then they started to ignore me and after a while I started to feel stupid. ,M: Oh, you shouldn't. Your German is really good. ,F: But it seems they were using their German ability to have fun with each other. They didn't really want to include me. ,M: Well, some people are like that. That's all.
