Search Results: minding own business

So my daughter takes the bus to school and back everyday. Her bus route takes one transfer at a big intersection where many other students also wait for the bus. Every week or so, she notices a man at that intersection waiting for the same bus. He tends to stand near the girls (but not overly close, maybe 3 feet away) for a minute or so and then walks away and then stands alone. Very odd behavior, and he did that with my daughter once. She gave him a mean look and he walked away, and hasn't stood near her again since then. He doesn't stare at people or anything, but his behavior is odd, though most of the time he is standing alone, apparently minding his own business.

But the greatest oddity is that every week or so, she sees him at the same intersection waiting for the same bus as her after school as well. Thus he does this when students are waiting for the transfer bus when going to school and also when they are waiting for the transfer bus to go home as well. This surely doesn't seem like a coincidence and that he is timing his visits to the bus stop only when he knows a crowd of students will be there. And another oddity is that she has never remembered seeing him actually getting on the bus either. Though there are different buses and maybe the particular bus she gets on is not the bus he's "waiting" for, it does seem very peculiar indeed.

So what can we do about this? We thought of informing the principal of the my daughter's school, but this intersection is pretty far away from the school and is probably none of the principal's business. So report his behavior to police? But he's apparently not committing any crime or causing any harassment, so I don't see what they would do. He's also not there everyday, so police would have to stake out that intersection for a week or two before they finally find him--a costly operation unlikely to happen since they don't even have anything on him. We are at a total loss about how to deal with this.
