Interrupting

It is easy to forget that others are having a conversation when they are speaking in a language foreign to you. The result is that the "foreigner" may interrupt at will with a new topic of conversation, as if the other conversation was not taking place.

This is true whether the "foreigner" is actually able to speak the language of the original conversation or not. However, this only happens when the "foreigner" is not following the original conversation. Nevertheless, given that it is difficult to follow everything that others say in a language foreign to yours - even if you have become fluent in that language - you may still find yourself interrupting conversations without meaning to, when you are already fluent in that language.

I said "foreigner" because I do not mean that you have to be in a foreign country to do this. You may interrupt foreigners as they are talking in their native language, or even people from your country who are speaking in a language foreign to you.
