A lantern with horns that can hold ten thousand drops of water is sitting on the ground. You get closer and realize it's not a lantern, it's a bottle. It's got horns, and a weird handle, but it's definitely a bottle with water inside of it.
Even though you're not the one who left this bottle here, you decide to do the right thing and throw it in the trash bin (びん). It's not right to leave a bottle just sitting on the ground, you know.
