#Person1#: Hey, Jenny, what's the matter?
#Person2#: 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.
#Person1#: Oh, you shouldn't. Your German is really good.
#Person2#: But it seems they were using their German ability to have fun with each other. They didn't really want to include me.
#Person1#: Well, some people are like that. That's all. You can't let them bother you. One nice thing about chat room is that you can leave and go to another one.
