What's he doing, and where...?

It's after school, so I think he is spending time with his friend?

Friend?

He has friends within the school?

No, he doesn't talk much with anyone at school.

... I don't think we need to worry too much about what he does outside the school.

He has made friends outside the school and...

They do not have a harmful influence on him.

Come to think of it...

That thing seems pretty hard to catch...
