Even if a cynic never experienced any kind of disappointment within their own life, there's no telling who they've met whose own stories could color their outlook. I honestly don't believe that anyone could be born to just always have a negative outlook. I know I wasn't. I used to believe in things. That changed in my teenage years as it does for many people.

Sometimes, people develop a "contrary" personality in order to balance out someone of the opposite extreme that they spend a lot of time with. Possibly, your pessimistic sister developed her personality as a way of coping with your optimistic sister.
