     "Imagine when you lived at home with your parents. Everything was right there when you needed it (like local file storage). Let's say you're about to move away to college (the cloud), but you have decided to backpack there and so you can't bring any of your belongings with you. You put everything in your parent's (infinitely large) garage (cloud object storage). Given you would need to have things shipped to you, would it be better to leave everything unpacked? To put everything all in one box? A few different boxes? And what would be the most efficient way for your parents to know where things were when you asked for them?\n",
