On my first ever solo overseas adventure, I happened to be allocated a seat on a Boeing 747 next to the friend of a friend.
We went our own ways in London, but ran into each other in the streets of Bloomsbury just two days later.
In Bangkok one day in June, 2016, I was waiting at the BTS (sky train) station, and when the train pulled up and the doors opened, one of my oldest and dearest friends jumped out at me.
And what are the odds that my nephew in Australia would spot me in a holiday snap one of his colleagues was showing him?

The best thing to do is to go with the flow.
