Fan Casting No Social Skills in Sort by Tropes

For some reason, the character is mostly ignorant of and often confused by common social conventions and behaviors. They usually grasp enough to minimally function around other people most of the time, but any circumstances outside of their limited experience fluster, puzzle, or (at worst) upset or enrage them. Someone with no social skills is not necessarily stupid — just unfamiliar with how human beings act around each other. Consequently, they will tend to be blunt, straightforward, and Brutally Honest. They will expect everyone else to be totally honest, too. From a writing point of view they are an asset: they say things that everyone is thinking but no one would dare say out loud.
