A little back story about this matter. I had been going to the gym everyday at a certain time. There was this older man that I would run in the same row as and he would sing a long to his music. I would look at him a few times hopping that'd make him stop singing but it didn't. A few months go by and all of the sudden out of the blue he comes up and says to me that he notices that I've been doing well and to keep it up. I kind of shook it off but considered it kind weird in a way and decided to change the time that I go. I go a few days at this new time and the one day I was going to my car, I hear a car honk. I look around and its him just getting out his car and he waves. I just kind of wave to be nice and get in my car and drive away fastly. I decided to change the time I go again and went later in the evening. He came in one day and saw I was there but didn't say anything. I went on to go at this time for weeks without him being there until yesterday and today. Yesterday he comes up to me and tells me that what I'm doing is good and to make sure to come. I was amazed that he would do this yet again and couldn't wait to leave. Today I go a little earlier then today hopping that I don't run into him and I do. At which he tells me that I should say hello to him and that it would make his day. I was going to tell the people at the gym before I left about this but he was still there so I didn't really want to say something and then he comes after me or something. I do though feel like I should say something to them. I've tried to just ignore it or go at a different time but that hasn't seemed to work. My question is how much will they be able to do? I guess I just worry that he'll end up stalking me because of this or something. It may not happen but you never know. Is there any other measures I could take? Thanks!
