I know exactly zero jokes or innuendos in Russian.
You also speak zero Russian. I, on the other hand, am here, conversing with the natives in an almost-fluent way where no one would suspect I'm from anywhere else on the planet. Then I'm given shit over my E being SL because I didn't get a local reference.
Dude, get me: I'm not trying to make it seem like you did a bad thing. Your explanation helped. The matter is: I'm supposed to be good at this, with you in particular praising my fluency in plain text. Even if I wasn't, what the fuck does it matter if English is my second language? Does it make me a second-rate speaker all of a sudden? Of course not - and I don't appreciate being treated like one over a small misunderstanding.
