At another mobile bookfair, (I know I know, how mobile is it when some bookfair always seems to be a permanent fixture near my office? Hey, invite me over to wherever you are, maybe the mobile bookfair will follow. lol) I saw an Opera guidebook and decided to buy it to get acquainted with the plots of operas (the long-lost siblings, the woman who was a man, star-crossed lovers etc). Then it turned out that the Opera guidebook comes with an Opera CD, as well as a Classical guidebook and a Classical CD. So I ended up buying them all. The lot was really too cheap, and though they're not my normal music preference either, I feel strangely indignant for them. Crazy. :)
