I was working out at the gym, been on the treadmill for about 20 minutes, I was about to get off of treadmill and start working on my workouts for the day. I was all hot and sweaty and I looked over at this group of girls and notice that one of the girls has her phone pointed right at me, and I could tell that she was trying to hide it. She had her phone on the top of the elliptical but she was on the row of machines in front of me so I could see everything, she had her phone turned around trying to sneak a picture of me with her back camera. As soon as she saw me look over at her she hurried and looked away, put her phone down and started whispering to her friend, as if to say "He caught me taking a picture of him". I brushed it off, but It just got me thinking that if the roles were reversed and she caught me taking a picture of her, I would be thought of as a creep and disgusting for taking a picture of a woman working out.
