Is this even possible to control?
Anyone else think this is a bit pointless, since it is really the parents/guardians of students who send in Howlers. And Howlers do burst into flames, still screaming the message, when not opened. I know it is meant to exaggerate Umbridge’s tyranny, and is film only so is non-canon, but I still find it pointless for my above reasons. TheTARDISLegilimens (talk) 20:02, November 15, 2017 (UTC)
