When I was a child, I was put in a program where a college student worked with me once a week. I don't know why I was put in this program or what the purpose was. I was very shy, I suppose she was supposed to help me with my shyness, I don't know; this isn't really the point.
One day, she took me to her apartment and fixed me some Tang. I didn't know what Tang was, I only knew that I had never tasted it before since my Mom never bought it for our family. I had somehow gotten the impression that if my Mom didn't buy it for our family, it was bad and wrong. I told the college student I couldn't drink it because it was bad for me. She was incredulous and asked what was bad about it. I couldn't tell, her, only that my Mom never bought it.
I realize now, that I had put it in the same category as tea and coffee and cigarettes and alcohol. Why? Because of the mind of a child; if my family didn't consume it, it must be bad for you. I perceived it as bad because it wasn't in our home.
I grew up in a church that taught me that drinking tea and coffee and wine is bad for you. They placed a value on it that I accepted because they told me to. Even when I would read things in the news that contradicted what I was told, my perceptions didn't change.
Then one day, I grew up and decided that I was capable of changing my perceptions. As I opened my mind to different perceptions, I read and studied and learned that it was okay to value things differently than what I was taught as a child.
I changed my perceptions.
I was told by those in my former religion that I was a sinner.
I told them no, I had only changed my perceptions.
