How do u feel about a person

How do u feel about a person who think she is very wise. Always like to teach people how to do things or act in their life. Will say people are stupid or lazy if people don’t follow her own way of doing things? Take advantages on people as much as she can. Always say don’t like other people to push her, say words to threaten her but the way she talk also like push people or threaten people. This type of people is worth for me to keep the friendship or just be a socialize friend?
