Why I use my wits

When I use my wits I don’t get into a fight. I use my wits because I am a good girl and when I walk away and they kept on following me I will ignore them but if he or she keeps on following me I will turn around and talk to them and ask them to go away. But if they kept on doing that to me I will go and seek help and get and a teacher and she will put them on detention.
