You were doing something and were with Inosuke, Genya, Zenitsu, and Tanjiro while doing it.

You five were doing whatever it was you were doing and then Inosuke and Genya randomly got into a fight and started beating each other up.

Zenitsu: "WAAAAAAAAAAAAAAAAAAHH!!"

Tanjiro: "Stop this, this instant, you two!! Why are you even fighting?!"

Meanwhile the only thing coming from Genya and Inosuke was angry noises.
