As a North African I will keep it no matter what size it is, if it’s a fridge box I’ll put it under a matrice (I have no idea why it’s just the rules) and if it’s any smaller then I’ll put random stuff in it and keep it under the bed or in cabinet or closet till it falls apart then I’ll replace it with a new box, no cardboard box of mine is ever getting thrown away brand new. Use it to sneak around military installations, what else would you use the greatest stealth implement ever for?
One of three boys here. We would take turns being in the box while the other two threw steak knives at it. We would also light it on fire then blow it out. My mother is and was… not competent. If not for the electrician who happened to be there that day our house would have been a pile of rubble.
