I am starting school in June and I am wondering what everyone carries in their backpack? My program is front loaded and I have to commute via bus/train. I am trying to pick out the right backpack but not sure what size to get? I have a macbook--but what else do you carry for school? I am not very big girl (5'4" med build) and I look ridiculous with some of these big backpacks on--my husband found it quite amusing. I know this is a silly question--but I am trying to focus on silly details so I do not completely stress out!:saint:
