On the train this morning I happened to sit in a 6-seat part with 2 teenage boys, who needed 4 seats just for them and all their stuff! They were en route to the International School, and so talking together, quite loudly, in English.
As I joined them, their conversation was about whom they would kill in their school given the chance. Apparently the main criteria seemed to be if they were enemies or "stupid". One boy in particular was agreed to be "stupid" and so deserved to die.

In some countries those boys would probably have been reported and arrested, but it seems to be just fantasy. I think if they were really planning something they would not plan it on a packed commuter train.

however, they did change the subject quite quickly after I asked them to pass me a paper and they realised that I was English 8|
