If you live in Salt Lake City, and you have ever been in High School, you already know. People from here tend to be extra shady, very confusing, or act like nothing is wrong when something is.
Sometimes this can include going from someone wanting to be around you, to wanting to stay away from you. You'll ask if something is up and if they still want to spend time with you, they say they still want to but always make an excuse not to.
She's not going to be honest with you because this is Sus Lake City we live in.
