I used to carry my home on my back, in my backpack, along with my laptop, my mobile phone, my tablet and the mouse. Sometimes the backpack got a bit heavier and then I stoped to connect the laptop and the phone and the tablet to a wall socket. Once, when all the mobile devices were grounded, I counted three continents and seven countries and twenty-three different doors and they all opened into Home. But in all of them only the mouse felt really free and happy, because in the end all he needed was to replace a battery.
