Charlie tends to be rather independent and self-reliant, usually going off by herself. She is also sulky and rather awkward, finding it hard to open up to others and having a tendency to sink into herself, getting lost in her own thoughts. While Charlie isn’t shy, she often gets nervous when caught off guard by people and tends to toss out non-sequiturs. She also finds the constant company of others somewhat tiring and is intimidated by those who are polished and immaculate.
