They are not the same thing, but as I said lady I am far from naive. Not basing this off my personal opinion or belief, but it is a fact. In fact, to prove it I took a psychological-based test online and the results came out to be I am very realistic. Not naive. I'll even do you a favor and copy and paste the results on here just for you to realize.
Your Result: You're Very Realistic
You're not naive at all. You take a situation or a person as it is. You can see the truth in something-even if it's painful. Some may call you a pessimist but you're just trying to protect yourself from the world.
