a lot of people have a reading habit. observing them in the train is somewhat interesting. the books they read, their postures,...everything. but one thing i personally can't accept is people folding pages in the book instead of using a proper bookmark. (yes, if you are about to borrow my books, watch out!) but there is one exception now:
Book Origami by Isaac Salazar
this is simply beautiful. not gonna unfold it =P
