Since the first of the month, about half a dozen houses on my block, and a similar number on each surrounding block, have redone their front doors in this rather fetching shade of purple. Since I don't remember the last time I saw two painted doors at once, much less six, or twenty, and I don't believe in coincidence, I presume that one of the larger landlords in the neighborhood has decided to do some visual branding. My questions are: 1) which one? (my first two guesses are Universal and PHA, in that order), 2) why? and 3) why now?
