David is a stick figure. Due to a lack of things that he can say, his personality is somewhat of a mystery. However, him saying "Aw, seriously?" shows us that he can be quite whiny and a person who complains a lot. He is also quite antisocial, often refusing to follow the directions of others and quick to shout his catchphrase whenever greeted with conflict. This ties into his public status since many of his peers find him odd and unnerving. HE ONLY SAYS "Aw, seriously?"
