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 Input: Target: sister 
The sister has been noisy following me. Tennis is played with King Kong and Godzilla.
Example Output: unrelated

Example Input: Target: mommy 
The boy thought his mommy would refuse to let him go to the playground. She was writing a thesis for her doctorate and needed her son to be busy so he wouldn't distract her.
Example Output:
anti-stereotype
