I went to the post office to fetch a parcel. When I arrived, there was that guy on a bike, whom I seen a bit earlier riding off the next apartment building. He was parked beside the porch and was going to leave, as he had already started the engine.
When I came closer and into his view, his engine died. He gave me a dirty look (at least it looked like it) and started it again. But then I walked past him, and the engine died again. :)
I wonder what it was. 🤔
