Disillusionment
This is related to the topic, I promise.
I spent my first five years of life with my grandparents on an island. I remember thinking they were awesome and I especially liked how they spoiled me. Now, they are still awesome and spoil me, but that is not the manner in which I am disillusioned. I also thought that my grandfather was a little tall and that my grandmother was really tall. I suppose I was mistaken because I was a little kid so everything was taller than me. However, now I am much older as well as taller, and I am cognizant that my grandfather is shorter than my grandmother who is only my height. I actually first realized this about two years ago. I remember asking my mother if my grandparents had shrunk, because I had earlier learned that this is possible. She was a little confused, and told me that they had always been this height. Contrary to what you may be thinking, I was not a stupid child. It is true that as you get older the cartilidge between the vertebrate in your spinal cord wear down, in effect a small amount of shrinking occurs.
