Also, it seems alot of people really sympathise with Draco in this, but to me he seems somewhat unhinged, especially with the fanatic way he spoke in this chapter. He almost strikes me as bi-polar (I would know, I lived with one for nine years), except his forgetfullness in his office somewhat moves against that theory (most bi-polar are obsessive with knowing where everything is, and normally have very neat and orderly living/working space).
