People like me: you have my sympathy. You should also read this recent Pitchfork column by seemingly erstwhile scribe William Bowers. You will recognise many of the thought processes, anxieties, petty rationalisations and antisocial tendencies contained therein. (You will also note, with misguided satisfaction, that you are not the only person to obsessively alphabetise your "collection", and to know who sits next to whom on the shelves.)
One qualification, though. In the case of Maggie Gyllenhaal, I think I could turn a blind eye to the occasional Jim Morrison poster.
