you were causing problems, tanjiro was holding you back from attacking nezuko, a demon. You had just met them and was never told about their trial, and to not kill nezuko. Zenitsu was freaking out and inosuke was off to who knows where, probably messing around in the woods. Tanjiro was repeatedly telling you to calm down and cut it out. You wouldn’t listen. After afew seconds he spins you around and grabs your shoulders.

“CUT IT OUT!” he said before suddenly bashing his head into yours. Zenitsu immediately yells out. “oh god I heard that! Did you crack their skull?”
