Did you ever bump into friends or neighbours...while you were on the other side of the world travelling?
Did happen to me few times...years back I was travelling all over Asia and I bump in a youth hostel on one of my friend who was studying for 6 months in Korea...all this in Tokyo.
3 years ago, on a flight from Buenos Aires to Bariloche...bump in a friend from Vietnam...that's a very small world.
It does happen all the time all over Asia, but it's more fun when it does involved other continents...and that it's pure coincidence!
We met an English woman traveling solo, while we were in Aitutaki (Cook Islands) and, about 4 months later we saw her again in Bangkok.
Also, we did a glacier trek in New Zealand with some guys from the Netherlands and we found them again... guess where... in Bangkok!!!
Countless times in SE Asia and a few times in Europe too, but they were always people met both times while touring, so following a certain pattern.
But once, in Edinburgh, some ten years ago, I was travelling with this Aussie guy, it was winter, extremely cold, we checked in this guesthouse after a night-bus from England, it was still very early. We went to the commonal area to warm ourselves up with a cup of coffee, and as soon as we entered the room, my friend went straight to the only other guest present in the room, a fellow Australian sitting at one of the tables, and they greet and start talkin and laughin and so on. I thought it was the usual story: they'd maybe met in London a few weeks before and now, by chance they ended up in the same hostel in Edinburgh. But, No: they had been schoolmates in primary school back in Australia (countryside Australia, moreover), and they hadn't heard of each other for years. Now, the most magnificient thing in this meeting (that up to present days still remains the most umbelievable coincidence I've personally witnessed) was their reaction. They didn't jump in each other arms as two -say- Italians in such circumstances would have done, nor were they controlling their emotions, they were just natural. It wasn't what I would call "mild reaction", it was just people used to the extraordinary, I guess. It was probably the moment when I definetly decided that I love Australians!
Also, when I was a student and interailed around France and Italy I met a couple of students from my university when I was walking down the street in Marsailles.
I went to school in a small country town in Australia and bumped into two guys I went to school with at a train station in Berlin. I hadn't really kept in touch and had no idea they were in Europe. It was surreal but great as we spent the next few days hanging out together in Berlin.
I was served a beer in Auckland by a guy I'd gone to college with - (16-18 in UK) - to my shame - I didn't recognise him! until he made it really obvious and said where I knew him from 😊
We've not bumped into anyone we know, but my little boy was picked out of the crowd to help out a street performer in Queenstown, New Zealand. When I showed my husband the pictures, it was the same street performer (and act) he'd helped out with while in Melbourne on business a while back. Also, we were shopping in Norwich a few weeks ago, when a couple ran over to us and said they had been in Queenstown and seen my little boy helping out the performer (he is hardly a wallflower and helped to draw in a big crowd with his ad libbing and is very easily rememberd!). Turns out they live a mile away from us! Thought that was a huge co incidence.
