OK, speaking of creepy gym experiences, I got one. I used to belong to this gym, there is this guy almost thirty years older than me. First time, he introduced himself to me when I was doing stairmaster. Later, when we meet in the gym, he would greet me, and try to talk to me. He asked a few times to workout with me, and I sorta ignored or rejected him. Once, he finished his workout, sat at the registery table chatting with the staff. When I finished my workout, he immediatly stopped conversation, and chased after me, asked for my phone number. I ran into my car, and left.
A few weeks later
He called my house. I have no idea where he got my phone number, b/c I never gave it to him. Thank god that I no longer belong to the gym after the first time he asked for my number.
Story over, girls just watch out when you are at the gym.
