Bad grammar only bothers me when it's from somebody who is a native speaker. An initial habit I had, and many have the same, when moving abroad and speaking with non-native speakers is to gradually let your own grammar slip into their habits - gradually starting to speak some sort of pidgin English. Somehow, to me, English spoken poorly by a native speaker just sounds grating. By contrast I never had this feeling with non-native speakers. Well there is one exception, when somebody is a non-native but speaks English near flawlessly, then suddenly their mistakes start to become somewhat unpleasant again! Maybe it's like music in some way. A cacophony is not unpleasant at all, when that's the majority of everything (tell me you're a death metal fan, without telling me you're a death metal fan), but when an otherwise clean and smooth rhythm or harmony is disrupted, it sounds extremely unpleasant. For a specific example, the intro to the song Cemetery Gates [1] practically ruins the song for me. It's such a beautiful and pleasant first 1:32, but then the dirty bit hits, and it's just too much. By contrast the transition at 2:31 is smooth, and so it sounds great and pleasant. [1] - https://www.youtube.com/watch?v=cSZf8ZYHV7o https://www.youtube.com/watch?v=cSZf8ZYHV7o
