...it's really such a small observation but struck me as odd.
He was standing next to a place where my DS and some older kids were playing, watching the older kids very closely. He stayed there for a few minutes, then moved to a different area of the playground and did the same thing. Then a few minutes later he did the same thing again. He didn't appear to be accompanying any children as he didn't interact at all. Of course I could be wrong - although no children went with him each time he moved, it is of course possible that he had kids in each of those different areas and was keeping an eye on them all.
Anyway, putting it in writing it feels like a non-story but it just made me feel a wee bit uncomfortable at the time. As ever, when you notice something that you think is a bit dodgy, you then interpret everything about that person within that prism - so I would say that he did look a bit shifty, but then maybe my mind was just prejudicing himself against him.
That's all. No need to reply, just wanted to get it off my chest.
