Today someone changed my opinions on how I thought. I wish this would happen more often. I'm tired of trying to find answers to justify my opinions only to win in the end-- and rewarded by being told that I am "right". I like being proven wrong believe it or not, as long as it makes sense and there is grounded proof and logic to why I'm wrong.
Oh to be older, and to be filled with wisdom. That is what I wish for.
