This reminded me of something really weird that happened to me one day. So there was this group of my friends in a cod lobby and some random person joined. We all added each other and started talking in a party. I thought "she" was a girl because "she" had a really high pitched voice. So somehow the topic came out about guys stuff and I was like why r you guys saying this in front of a "girl". Then I realized that "she" was a guy and I left immediately.
