anablog
An old-fashioned journal made with crushed tree pulp, binding, and maybe some kind of locking mechanism. It is a fad past its prime but Borders still sells them.
Girl 1: What is that rectangular-shaped device you have in your lap that appears to be filled with blue-lined two-dimensional peces of nondigital substance?
Girl 2: Oh, this is just my anablog....I write in it to remember things and keep my private thoughts.
Girl 1: I see. So how do you post it when you're done?
