period in white clothes

this isn't my story but my god sisters. So we had to go to this all white event and we had to wear white(duh) anyway while we're at the event she was like come to the bathroom with me. so she got up and there was blood on the seat and blood on her pants. so i put a lot of napkins on the seat and hug her from behind. she ask me what i was doing and i said lets just go to the bathroom. so i grab my bag and rush her there. i had my period way before hers so i knew to keep extra pads on me even if im not on it. i got her cleaned up and we told her mom then we left. the end.
