We are often more multi-dimensional than what is on the surface. We have more substance than what is on the surface. We are 3D shapes; we have many sides, many edges, and we have a volume, not just a surface area. We are deeper than what we show. It's easy to say "You don't understand me", but what about the moment when you felt that it was the other way around? Sometimes, you understand someone less than you think you do.
Sometimes, we look at what is shown on the outside. We see the images other people try to portray. We see different sides to them. Sometimes, even worse, we only see one side of them. We make judgements, and then we feel intimidated and we avoid these people. But it's unfair. We haven't even got to know one another.
There's this person I had always judged. I used to see a few sides to him/her. One day, I gave in to my insecurity, and I felt that I could not open up to this person because of a few actions that he/she had done. I avoided him/her and gradually my view of him/her became shallow. From then on, that person was flat to me. There was only one thing I know when I see him/her: He/she is a hypocrite. But there was more. Everyone has a story in them, they have depth, deep thoughts, feelings, soul, and all those stuff, and judging from the outside is just wrong.
And then I opened my eyes and saw more to this person. I had always felt that this person was unemotional, one-sided, superficial. And then I saw another side, and yet another side, and the emotions start coming. I feel guilty for what I've felt.
We are all 3D shapes. Even in creative writing lectures, we learn that characters are multi-dimensional. There is always more to a person, that's why people are so intriguing. There is always more to a person, that's why we never fully understand one another.
