One year ago I read a short story (really short, like a few paragraphs) that I'm trying to find again. The story was about a crew consisting of different alien races, including the human race, and started with the other species bullying humans for being weaker. Suddenly there was an attack on the spaceship and things went south but the Human proved to be extremely brave and tough and saved them all, gaining recognition as a species to be feared because of their courage. It was a really short story that I found on the internet, I think probably just something that someone wrote in a blog or something, not even published.
Does it ring any bell? I'm dying to find it again but google isn't helping me much.
