If a girl calls you her friend but she barely knows you and asks you to do stuff for you what does this mean?

It means she in way over her head. If you do not see this girl as a friend you have to stop doing things for her. She probably doesn't have many friends and thinks that since you may have hung out with you once, you are automatically her best friend... not to mention only friend. Just tell her that you don't have time to do stuff for her because not only do you barely know her but since when are you her bi*ch?

Hope that helps
