<human>: So the other night I was standing outside the Cinema's bathroom, having just seen the spectacular film that is Interstellar. I was waiting on my friend to finish using the restroom, and I see a guy push open the door to the girls' restroom. Being a considerate guy and a fellow bro, I tell the guy that that was the girls' restroom. This guy turns around and looks at me, and she politely tells me she is a girl. I freeze up and look back at her and tell her that "oh no, I was talking to my friend here and face my friends awkwardly while blushing". Suffice to say, my friends did not let me live that one down...

Can you condense the text into a few key points?
<bot>: Stopped a guy from entering the girls' bathroom, only for her to correct me and prove she was not a guy...
