If two of your best friends quarreled, what would you do for them?

your two friends?you mean they are lovers?if it is,that will be more complicated. but if not.i think the first step is to make sure what problems are between them.is there a misunderstanding,what they are quarrelling for? get to know the source of the problem,then,make some chance for them to clear it,and say it out. i guess both of them need to cool down before they can listen to each other.

I don't want to make things worse. I won't take sides. I'll choose in the middle. I also don't want to interfere with their situation. Both of them are your best friends. It is better to take a safe position. If you are trying to do something, one of them or both of them will not like your solution. The best thing is to put things neutral.

let them cool off and im sure in due time they will come into their senses. as the saying goes let it be and when the time comes it will just happen
