Article 10 : A Bro will drop whatever he's doing and rush to help his Bro dump a chick

It's normal for a Bro to get confused and disorientated when dumping a chick. For some reason he's worried she'll become agitated or even violent after he calmly explains his desire to have sex with her friends. This is when a Bro most needs his Bro to remind him that there are plenty more chicks in the ocean, and that a breakup need not be hazardous, stressful, or even time-consuming.
