ah, kids these days! Why didn't they beat the sucker down and take his knife too! It just goes to show you, never send boys to do a man's job.

Seriously though, he is very lucky they didn't take his knife and used it to cut him up.
That is if the story that he got jumped is really true.
Excuse me for being a sceptic, but so far it is just have his word for it and the story might be that he attacked the kids with the knife first.
