I have been going to this gym for the past 4 months and there is this guy whose is following me. He also comes there for his workout and around my age (i.e. early 20's). Its been happening since I have joined the gym. He would come to the room where I'm exercising and then he would stay there do nothing and not use any equipment. After few minutes he would leave the place. This other day I was doing weights using the incline chair, he sat right next to me and was staring at me. I tried ignoring him and then he started doing weights. I don't know whats up with him. We don't talk to each other and we don't know each other. Hes not following me everyday but occasionally.
