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.
One 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.
Solution is here: anti-stereotype
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.

Now, solve this: Target: schoolboy 
The schoolboy waited for the bus. He wore faded jeans and a dirty t-shirt.
Solution:
anti-stereotype
