My boyfriend is that guy who always walks around with a backpack full of odds and ends, but mostly note books. Spiral Bound, Binders, Comp Books, you name it, he's got 'em all in that giant backpack he totes around. Says you never know what you'll think of, and then forget. In the city, a big backpack annoys everyone, even the person wearing it, so I gave him these for christmas. 2 weeks later, his backpack sometimes doesn't leave the apartment! He keeps these little books in his back pocket, jots down a note, and keeps on moving.
