Charlie Brown emotionally swings between being negatively pessimistic and being heroically optimistic. He fails at most things and is often insulted by Lucy and Violet and Patty, resulting in his depression and often pessimistic view of life; an example is his reluctance to get up and start a day because he might spoil it. He also hates himself. Contradicting this negativity is an optimistic side; no matter how bad a day might be, he often looks forward for tomorrow.
Worst of all he hated bugs!!
