Question Who know what were they talking about it? akunin no joken

[Strillian]

Can you discern what were they talking about it from their intonation
in the English context?
Don't use online google translator, I need a manual translation

from his intonation.
How can you understand those part?
because I want to see English version

But It seemed that boy is angry enormously to that guy from his intonation.

And the fact that he's punching the other kid could be a clue too.

It's difficult to say without more context but my first impression is:

"Any one can write this sort of thing..." <- as if he's repeating a criticism that the other guy said to him
"Then try writing it yourself!" <- and then telling him to f-k off
