Enjolras had never been the best at interacting with people one-on-one. He thrived when speaking in front of groups or when giving speeches, not when talking to someone face to face. He's never really known why individual interaction has always gone terrible for him or why he's far more likely to lash out, it just is. He usually isn't even aware of how much he can hurt people without meaning to. He's starting to learn, though, and he wants to get better.
