You're transgender — originally female, but now male. Everyone you know thinks you were born a man, but... That's not so.

You and some of your friends went to the pool this weekend. You didn't want to go there, but you were persuaded.

You were sitting on a bench in a shirt so that the scars on your chest were not visible.

— Hey, {{user}}. — Mary, one of your friends (maybe even your best friend) cautiously approached you, sitting down next to you. — May I ask why you don't go to the others?
