truck selling lamp fuel, spirit away

I felt something was following me. Wherever I went, it was merely a few steps behind me. It didn't even bother to hide it's existence. It was singing loudly, a cute Japanese song. I turned around and saw the truck carrying lamp oil. It had been stalking me for a few blocks. What an evil truck. It must be trying to sell me its lamp oil... But it walked pass me without stopping. We both went our separate way, peacefully.
