Have you ever met some or encountered someone one time, and then you start seeing them everywhere? Well one kid, who was kinda weird, had to attend my physics discussion because he had missed one or something (I don't know, not important), and now I see him everywhere. I saw him in my physics lecture, then my bio lecture, and then my archaeology lecture. I had never seen him before this but now I see him everywhere. If he was in my history lecture too that would be scary.
