backpack
A backpack is an ingenious carrying device designed to shove your belongings beyond capacity and affix a ruthless gravity training apparatus to your back. Though engineered for lightness, it effortlessly transforms into a repository for shopping bags, lunch boxes, and books, secretly subjecting its bearer to the torment of lugging it around. Praised as an indispensable tool for adventure, in reality it moonlights as a convenient excuse generator for daily errands. It demands the sacrifice of shoulders and hips in exchange for its moderate carrying power, making it the ultimate self-management tool.
