What a small world..

I've been to Edinburgh castle in Scotland, the UK. A unique local guide who was wearing a Scottish traditional costume took me to the castle and showed me around. It was so cool. I found a beautiful coat of arms and took the photo of it. Come to think of it, I happened to encounter some Australian tourists by chance. First, we met in London and had a small talk about our trips. They got to Edinburgh via Manchester, I got there via York. Then, we met again at the heart of Edinburgh by coincidence. We were waiting for the traffic light to change on the both sides of the crossing. So then, they recognized me and waved at me. It really blindsided me. What a coincidence. Small world.
