I wouldn’t say I have different English’s to the point where I’m speaking differently, as much as I have different manners. I would never pull out my phone to check a text message in the presence of my grandparents if we’re interacting in any shape or form. The constraints on this loosen around parents, especially when we’re looking up a fact or an article, and I can get away with checking my phone occasionally. And with friends, it depends on the group more and the respect I hold for them and that they reciprocate. I find it a good way to measure respect. But this is only the most obvious way to evaluate how I act differently with different groups. Many of them are much more subtle,, making them hard to recognize, but they’re all there.
