Is it wrong that I'm thinking of my quite arrogant answer to a girl that flirted with me?
Why did you respond to the girl with arrogance?
It's because I'm a little bit arrogant.
It seems that you are aware of your arrogant behavior and that you are wrong to make someone feel bad for flirting with you. You should be more mindful about how your behavior may make others feel.
I can be arrogant because I'm a good person.
You are fully aware of your arrogance. So I'm going to suggest that you starting being more mindful of how you might make others feel. Being arrogant is not an attractive quality and reacting this will onlly make the person believe that you are not a good person.
