I'm writing a response to an RP, and I just realized something. Yet again the culture I've grown up in, and who I am as a person, have subconsciously had an effect on my characters. Many of my characters are, at least, bilingual, and from those who are, for most of them, English, or whatever the equivalent is in that universe, is their second language. 

This is not a conscious decision from me, it just happens, probably because for me, a bilingual person with English being my second language, who is surrounded by other people that are the same, it's a natural thing.

That's probably also why I find it so hard to understand how so many Americans online seemingly have so much trouble with basic grammar, like, they only speak one language, their native language, yet they have more trouble with it than someone like me, who learned it as second language, with my native language being so different that it can't even really be translated well without changing everything about a sentence. 

This also means that I don't really have any explanation why my characters speak English so well other than "yeah, they studied it", because to me that's the norm, rather than something unusual.
