i get bloody noses a lot and i can usually feel it about 30 seconds before it starts dripping. today in class my nose started to bleed. but right before, I turned to this very religious boy who sits next to me and whispered “hail satan” as my nose started to drip. he freaked and fell back and hit his head. he had to go home for the rest of the day.
The same thing happens to me, but usually I just leave before if happens. I’m doing what you did from now on.
