Speaking as someone who's known diagnosed sociopaths, I wouldn't describe Tiffanys thus.
Sociopaths, despite of the consensus here, actually do have problems living normal lives, as they lack the capacity to observe structure and retain attention on what's in front of them. This is why many famous sociopaths have been on ADHD medication as children. They also have massive impulse control issues, which are problematical in general. A sociopath would be among the worst people in the world to handle money well or work in a technically complicated field.
