When I was 18, my folks took us to Greece on a sailing holiday, and we got friendly with the family on another boat. We went again three years later, and found one of the lead-boat crew (the company people) was the daughter of the family we'd sailed with that previous time.

Not foreign, but I've just found that my sister and I have both arranged trips to the Milton Keynes ski slope on the same afternoon. Since I've not skiied for 8 years and have never been to this ski slope, this is quite some coincidence!
