While obviously everyone misses information every once in a while, some people just really want to be heard. For the hell of it, I once made a theory on this; the less interesting the actual statement/opinion, the more volume they require to be heard. At some point a friend of mine chimed in with the claim there is a relation between a person's reading comprehension and how vocal they were about their concerns about the environment. The louder a person requires to be, the less attention they can give to what others actually have to say. Combined; these theories boiled down to the conclusion of every Greenpeace activist being illiterate.
Boredom can lead to amazing things.
