Little Concerns at the Inn

At eleven o'clock in the night, the lights of the rookie station were still on. After the shop owner, Liu, sent away the last neighbor who picked up the package, he found a small package covered with dust in the corner, with the addressee written "Grandpa Li from Building 7." He remembered that the old man had not come to pick up the package for more than half a year. The next day he came to deliver a package, and the person who opened the door was a strange young man - Grandpa Li left three months ago, and this package was his last online purchase of antihypertensive drugs. Da Liu returned to the inn and put the package on the highest shelf. After that, every Qingming Festival, he would wipe the package clean, as if guarding a piece of care that no one had signed for.
