You're probably right then, if no one was paying attention she probably wasn't trying to put on a show. My friends like that always made sure people were watching. For awhile when I was younger I was unhappily in a monogamous relationship with my ex bf, where I was kind of chomping at the bit and would do things like she is doing now. I felt like I was stuck with him and didn't have time to fully explore my feelings about women. Upon a second read of your thoughts, maybe this is closer to the case? My friends also felt uncomfortable that I was pushing boundaries with women at parties (the difference was just that I was openly bi.) I can't say much since I dont know her but maybe shes just like that but still closeted?
