I went on a date today with a girl who I previously thought was pretty cool at first. She then proceeded to tell me outrageous stories about her friends. This culminated into her telling me she only has friends for the benefit they provide her and is willing to betray and use any of them to get an edge. We didn't really vibe that well so this was it. Thinking back, I realize she has the hallmarks of a sociopath. She is my classmate and I plan on distancing myself from her.
