Anything wewe want... journal entries, taking notes in class, doodling, uandishi stories, songs, au poems, uandishi things down that wewe don't want to forget, keep track of your inayopendelewa quotes, use it to make lists, make paper airplanes... the orodha goes on. :)
Maybe a diary, au maybe notes for school au for hobbies like if wewe write. au maybe wewe can use it to draw, that's what my cousin does. Just doodle with it. Use it to do your homework on. Anything wewe want!
