Oh man I hate those things! Something similar happened like that at my school, except they'd say they died of something random on the announcements, and they'd walk around school dressed in black with white faces.

I didn't know what was going on, baked as fuck as I remember, and they first announced that my ex gf died of annorexia that morning, I was freakin out till I saw her after that class and was like god damnit wtf.
