Hold your tongue Never speak English to anyone who doesn't speak English, not even a wold if you can hold it. Otherwise what you could get, in any rate, is partial praise, sarcasm, or jealousy. They don't know English, or at least less than you do, so what's the point of speaking English to them. It would be like being an interpreter, you spreak Chinese to an English speaker, or vice versa. If you can't help it and speak some English to those non-English speaker, no matter what their attitudes are towards your doing so, they are most likely to secretly tell you to go home and speak to yourself. And the most advisable thing for you to do is exactly to go home and speak to yourself.
