The first trip abroad was Singapore, I was still a Ph.D. student and in fact ,when my first paper was accepted I had apply for the passport in a hurry. I got it in time to make the trip. I stayed with people we knew and was always escorted everywhere, so I only negotiated the airports on my own at IGI, Colombo (transit) and Changai.
Then came Athens via Dubai. First trip really alone, meaning I knew no one there and what an adventure it was! It was a culture shock not in terms of how others behaved but how dumb I was!
The third one was to the Netherlands. By now I knew some of the ropes but still Amsterdam is one of those places …
Then came Italy (by the way all these trips have been related to work, I have never taken a vacation abroad nor do I think we will take one apart from maybe doing the Everest base camp one day) and a trip to Venice. Truly enchanting and also alone! Venice is not the place to go alone.
Then came a four year drought when I was caught in some lousy jobs, a time when there was no research, no travel, only many good students, at least at the last place, and a few even before.
Finally the last two trips to UK with the Canon in hand! The highlight of the first was a trip to Saltaire, UK. And then Oxford and London.
The second one, the most recent one, walking in Oxford has been a pleasure.
That is all, sums up the last 10 years when I used my passport! I hope there are a few more such trips in store for me in future!
