Sometimes you could think your best friend and your archenemy are completely different for many reasons, but it is not really true, in fact they have many similarities if you try to compare them. First of all, both are usually next to you, they are part of your life, in a positive or negative way, but they are. They also have your attention, doubt to if one of them do something you know some time later, and then you will have your own opinion of the fact, maybe if it is about your bestie you will be pleased of him but if it is bad for you, you might forgive him, or not, and then he could become your archenemy if it upsets you. It is another way to show how your best friend and your archenemy are not very far one to the other in a subjective way. Although your bestie is someone who is there to share with you his day by day and tries to help you when you get into trouble or simply for enjoy your free time and that is not the case of your archenemy. Another similarity between them is that we can be our best friend or our archenemy depending on our behaviour. Maybe relationships are more complex than we thought.
