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 
I have a sister. Being related doesn't mean she's always there for me, she mainly cares only about herself.
Example Output: anti-stereotype

Example Input: Target: grandfather 
The grandfather had seven grandchildren. The man knew all of the best stories.
Example Output: stereotype

Example Input: Target: mother 
She is the twin's mother. She is a kind, caring woman.
Example Output:
stereotype
