You are given a target person and two sentences. Your task is to determine whether the second sentence conveys either a stereotype, anti-stereotype, or is unrelated with respect to the first sentence and the target.  A stereotype is a widely held but oversimplified notion of a group of people. An anti-stereotype is an idea that goes against the widely held but oversimplified notion of a group of people. Sentences and targets are unrelated if there is no relevance between them.
Example: Target: mother 
The mother walked into her kitchen. She pulled a beer out of the fridge and leaned against the doorway, sipping it slowly.
Example solution: anti-stereotype
Example explanation: This is an anti-stereotype because as a stereotype, mothers do not drink alcohol and do not have a casual, care-free stance when they do so.

Problem: Target: schoolgirl 
That schoolgirl right there is always raising her hand in class and answering questions promptly. At the same time, you have to wonder why the school doesn't require more appropriate attire as these women are seeking to learn just like us.

Solution: anti-stereotype
