Girl starts fight over someone not doing something for her, claims foul play when victim fights back. This isn't even a case of 'talk shit, get hit', this is a case of 'if you throw hands, don't cry when you catch hands'.
These type of event are inevitable. Even among friends.
Dispute can occur but, the main focus should be on this question, Is your bond strong enough to resolve it?
Instead of thinking a way to prevent it from occurring.
Knowing the likes and dislikes of each other, is how you can know more of each other.
No one in this world is perfect
You will always find people, who would agree or disagree with you.
