What is up with these people

So I’ve seen a lot of stories on this sub of people noticing someone or a group of people watching them in a public place for days, or weeks, or months on end and the person being watched confronts the person/people watching them and they have no idea who the person is. Why tf is this so common. It sounds like something out of a movie. Anyways, my main point is that if you see someone watching you for days on end in a public place just talk to the person next to you in the coffee shop, or the guy sitting across from you in the bus, or someone standing next to you in line in front of you and ask them if they’ve noticed the weird guy watching you and the worst that can happen is that they’re in on it and will just play it cool and tell you to mind your own business<br><br>Edit: I understand that some people in these situations are noticing someone or a group of people watching them in a public place over the course of weeks and months but I didn’t think of that aspect when writing this post.
