Last night, I was waiting for a bus at Shibuya Station listening to the tunes of street musicians playing near the bus stop. After two songs, she folded her score notes and halted. Just then another street musician standing about 20 ft away from here started playing. I've noticed these two were taking turns to play their music.
At first, I wondered why these two don't stand further away so both can be playing at the same time. But then I've noticed the girl has always been playing at the same spot at least on every Thursday. She has her own spot where all her fans gather around. I don't remember seeing the other guy but perhaps, it was his spot.
Seeing these two and imagining how they have made this protocol reminded me of how I've iChatted with my friend over an iSight.
