Feelings

Why are some events so unforgettable?! Why are there days that people never forget?! Why are there these outstanding days in everyone's life?! Well, I guess I know the answer. Let me explain, but first let's imagine we are robots. We are built to do tasks and whatever we should do. When a mission fails, we are programmed to do the next thing right. Occasionally, if we do something unneeded, we can just erase it in the blink of an eye. It sounds very easy to forget wrong things and to reach new goals, once you are made to do only what has to be done.
Let's imagine humans now. We all know that everyone does make mistakes, even though it's the last thing we want to happen. So, let's imagine that someone makes a mistake that is very serious. How do you think this person will be?! At least disappointed. She might want to forget it and move forward, but my question is: is that gonna be as fast as the click on a botton?! Absolutely not. You know why?! Because humans have feelings and this eight-letter-word changes everything! If a robot makes a mistake, which would be rare because it is not made to do so, it would forget it in the click of one botton, yes, delete it!
There are some days in everyone's life which are very special, because they involved our feelings. Doesn't matter wether you cried or laughed, if it can be forgotten, that's because it involved your feelings so much. That's why it can be hard to just forget things, because we probably did that with our heart and soul, and if it fails, we want to know why. It's the nature of the humans.
