This guy, Brad, at my acting class was interested in this one girl, Emily, some other girl, Courtney, found out about this and told Brad that Emily was a lesbian. I asked Emily if this was true, I brought up Brad because Idgaf about what this would do to him , and Emily said no but didn't want me to talk about it. One thing that stood out to me was that Emily said something earlier as a response to something "I don't like serving men" in a certain tone that made me think she despises men, meaning she could be a lesbian. Why would she say no? Could she be lying and trying to save face? Or does she know about Brad liking her, and by me not talking about it he wouldn't know she's actually not a lesbian?
