So you speak the world's new lingua franca. Perhaps you are entirely, or essentially, monoglot. But that doesn't matter now, does it? Because everyone speaks some English, don't they? Or enough people around speak enough of it to get around anyway. Why do I need to learn these other troublesome, pesky small languages?
Well if you would just care to observe carefully---the next time you speak to someone whose doesn't have native-speaker proficiency in English---how different they sound out of their native language. They usually sound hesitant, timid, withdrawn and a little defensive, no matter how extroverted, lively or, bold they may be in person.   If the conversation was initiated by the other person, in another language, you may well be able to feel the brief, but palpably awkward, slightly disappointed silence after you reply in English: oh, we don't share a language.
Of course you don't actually have to care about all this. As long as I get my message across, what does it matter? But you know, it would only be nice to take notice, and to at least try to bridge the gap.
