On a rainy day, I had to go out, so I retrieved one that hadn’t been used for quite some time, folded into a tangled mess resembling pickled vegetables. Upon returning home, I casually placed it in a corner to air dry. However, after several days had passed, a sudden twinge of conscience hit me. Wanting to restore it to its pristine, new umbrella appearance, I gritted my teeth and, with sighs, began the challenging task of folding the umbrella. It folded with such difficulty that it felt like my fingers were on the verge of breaking, yet the umbrella stubbornly retained its resemblance to a tangled bunch of pickled vegetables.
