I love Brennan's commitment to reminding you that he was hideously bullied for being a fucking weird nerd, ESPECIALLY when you're watching content about how outrageously successful and beloved he is now for being a fucking weird nerd.
Dita Von Teese was so right, you really can be the ripest, juiciest peach in the world and there's still going to be somebody who hates peaches. And depending on the social dynamics of your school, there may be a few high-status people who hate peaches who can bring enough people on board to make your life a living hell.
Brennan was bullied so badly that he had to be pulled out of school and homeschooled. Those kids hated his ass! And look at him now. What more proof do you need that being surrounded by people who want to kill you during your school years doesn't say fucking anything about how loveable you are or what your life will be like as an adult.
