Keeping Your Eyes Open

I just want to talk about a scary experience that happened to me on the 15 of July. I was entering a grocery store when I notice a man at the entrance of the store, he was alone and say "hello" to me, I took a glance, kept walking and enter the store. While I was shopping I notice him showing up on the areas of the store that I was in. So I started to keep a close eye on him. As I observed it was obvious to me that he wasn't shopping. He didn't had a shopping car or items basket, he didn't have a grocery list or items in his hands. All he did was pop up where ever I was and stared, I even acted like I was in the phone with my husband talking about dinner plans, then he got closed enough to comment on what we where going to do for dinner. At that time I decided I had enough. I found a policeman at the store,and told him about the creeper, he suggested that we take a walk around the store and point it to him. We did not find him my guess was that he saw me talking to the policeman and left.  I still took precautions and ask the policeman to accompany me to my car, because the man saw me entering the store and saw where I park. When the policeman was walking with me outside I saw the guy again, I guess he was waiting but to his surprised I pointed him to the policeman and he got him and told me that he will call the police to do a check on him.
All I want to say is that they are predators out there, just waiting for someone to walk alone and don't pay attention to their surroundings. Please keep your eyes open. Don't be afraid to confront the person or get help.
