The Laziness is Real
Now and then you come across a story of people being harassed for speaking another language. To which I say, who cares? and, it’s not your business anyways. I don’t know of any rules saying you have to speak any language here, nor is there an official language.
Why is it such a big deal someone is speaking in another language? Is it because you don’t think they are assimilating? Most people do. I’ve always seen it, and it happens much faster with kids. No one is trying to take over, stop scaring yourself stupid.
