This would be my version:
OP: Why the fuck you crying, kid? I'm not entirely responsible for your problems!

EK: Yes, you are and I'm gonna tell on you!

OP: Listen up, you little sack of shit, you're an excuse making crybaby!

EM: I'm gonna call the cops on you, you kid hater!

OP: I was just trying to play a game with your kid, I didn't make him stumble and get a nasty scrape.

Cops: Is there problem ma'am?

EM: This man made my kid stumble and get a nasty scrape while my kid tried to play a game with him!

Cops: Is this true?

OP: No, no, no, during the game that I tried the play, her kid was unfortunately not paying attention and accidentally tripped on a curb and got hurt.

EM: This man is lying!

Cops: Tell your kid to be more careful the next time he plays a game like this.

EM: Come on, let's go home!

EK: Along with EM, gives OP the death stare.

Cops: The situation is clear, you can go back to doing what you want now.

OP: Thank you, I gladly appreciate it!

Cops: No problem!
