Is it normal that i've reached this point in my life?

Is it normal that I've reached the point in my life where if I don't like someone I just want to ignore the person. I'm not interested in debating anything with the person, nor am I interested in proving the other person wrong or proving myself right. I just want to have nothing to do with the person, I'd be fine if the person just went poof and disappeared. Ideally I don't want to waste my time wishing the person was dead, or try to understand the person and make peace. I just want to ignore the individual, and I want them to fuck off and leave me the hell alone.
