In a story or play, the antagonist is the force against the hero or protagonist embodied in a character. This enmity or opposition is created by the external or internal factors that force both the protagonist and antagonist to be at odds with each other. The main goal of the antagonist in a story is to create obstacles for the protagonist sometimes even without apparent reason and justification for an evil attitude towards the hero.
That is true. Because you will not comprehend what the sentence/ words are saying, because you only care about getting it written down. So multitasking reading and writing at the same time is not a good idea :)
