Final answer:
The question seems to reference a character named David feeling a certain way on the board in the barber's chair, but the provided texts do not contain information about David. They instead discuss Bernice's experience and the general theme of societal perceptions, which could parallel feelings of being exposed or scrutinized.
Step-by-step explanation:
Based on the context provided, there isn't a clear reference to a character named David being on the board in the barber's chair. However, the references to Bernice in the provided excerpts indicate that she may feel out of place and the center of attention, as indicated by the reactions of the barber and the other patrons. Additionally, the provided texts discuss themes of societal perception and the discomfort of being seen as a problem by others. It can be surmised that being in such a spotlighted position, similar to how Bernice feels in the barber's chair, might make one feel both courageous and fearful.
