A lot of people think I either speak German or Spanish, when they see my username. I mean, I studied German for a bit, and I can understand simple or common phrases, but I definitely can't really understand it. More so, I just have an idea what people mean in German. Spanish, I grew up around my grandmother speaking it a bit, and trying to teach me it, I can understand a decent amount of it, but I also can't speak it. So, it's always fun how disappointed people seem to get. Speaking on that, I have had people trying to insult me in Spanish, but I still can understand more than they think so that's funny as well, I'll just reply to them in English. It's even funnier when when I am on a mic, because I apparently sound very "white". I guess it helps that my grandpa (who I was partly raised by) had a heavy southern accent, and I think I might have picked up a bit of it.
I do have different usernames though, and variations of this one. My ESO account for example: it has a more general username, and all my characters have lore friendly names, because it's Elder Scrolls. I like to do a tiny bit of RP when I play RPGs and Elder Scrolls especially. I have always done lore friendly names for it, and even think of light backstories for my characters. I'm one of those people who actually hates making goof characters, like in Oblivion even.
