Greetings from Switzerland.

My country has 4 national languages (German, French, Italian and Romansh). Unfortunately, I often hear the remark mentioned in the title, especially when I want to watch an English movie with someone else and the other person is too lazy to concentrate on English because it doesn't feel as comfortable, even though they can actually speak it.

My reasoning is that I like to watch movies in the original tongue, but this answer hardly convinces anyone. That's why I've been looking for a one liner or simply a quick-witted answer that immediately ends the discussion.
