Virtually every white person you meet was a nerd in a high school-it it is how they were able to get into a good arts program and law school. As such, their memories of high school are painful, but not tragic since they were able to eventually find success in the real world. Exploiting this information is your one way to ticket into the heart of a white person.
Your first priority must be to steer the conversation to the topic of high school, which is not very difficult. If you are talking about music, mention the music you think they would have liked in high school and how you were taunted for liking those bands. If you cannot properly gauge the type of music a white person liked in high school, you should always say that you were really into The Cure. All white people know that liking The Cure in high school is an invitation to be tortured by the cool kids. This will bring about instant sympathy and respect.
It is also acceptable to discuss how you were in love with a cool kid who never loved you back. For added effect, you can mention how said cool kid is now doing very poorly and that you are excited for the upcoming reunion.
If these first two points were not enough to gain an adequate level of trust, you can close the deal by saying: “I was the only <insert ethnicity> kid in Improv/on the paper/on student council.” Wait for a sympathetic look and then you will know that you have forged an unbreakable and easily exploited bond.
For maximum effectiveness, this technique should be used in a social group setting where everyone can share their stories. By guiding the conversation, you will be seen as a natural and sympathetic leader. This can be easily exploited for professional and social gain.
Note: In the rare encounter that you meet a white person who was “cool” in high school, do not panic. There is a 100% chance that one of their other cool friends sold them out in a coup for control of their social circle. Failing that, you can exploit the inherent guilt they feel about their treatment of nerds.
