In general for me travelling is almost more about getting to know people than places. I am a huge fan of Couchsurfing and use it whenever possible to connect with locals. Some of my best stories include the following, but to be honest it was hard to make a choice as there have been too many great stories so far.
I experienced the largest hospitality which really overwhelmed me during my trip to Iran in autumn 2015. I have never in my life received so many invitations for tea, meals, sightseeing, conversations and even stayovers. Now I am curious if this can be even topped by another country to come.
I also remember my trip to Surabaya on Java, Indonesia where I visited some Indonesian friends of mine. They brought me to their German school and I really was the first German person most of these pupils ever met in their whole life! They even sang a German song for me and asked me so many things about my home country.
Another thing I remember was on my first day in Havana, Cuba when I was sitting alone on the Malecón listening to a trumpet player. I then started to talk to him with my almost non-existing Spanish and he then invited me to have dinner with him and some friends in his barrio which was my experience of the real harsh life of locals behind the Tourist scenery. Although everybody was nice to me I had a strange feeling in my guts and in the end they let me pay for all the ingredients and some rum, but luckily let me leave at the end of the dinner. It was just afterwards I found out I had been in the most dangerous neighbourhood Marianao where tourists are absolutely not recommended to go. Once again my curiosity to meet people was much stronger than my prudence.
In terms of pure mass of people India made the largest impact on me. I have never seen so many people, vehicles and animals on the streets day and night with so much noise, action and also dirt in my whole life. Especially if you live in a country like Germany this results in a kind of cultural shock persisting for the first days until you get used to it.
Another interesting experience was spending a couple of days with a German friend of mine who became a Bedouin living with the local tourist guides and souvenir shop owners in the beautiful rock-cut architecture city of Petra in Jordan. He and the guides took me to unknown parts of Petra even outside the official visiting hours, told me funny stories about the behaviour of different nationalities of tourists and took me out to the dessert close to the Israeli border for an unforgettable night outside below the stars around a fireplace.
One more incredible experience was staying in my favourite city St. Petersburg (at least in the warmer half of the year) during the White Nights around mid of June for a total of three times. This feels like magic and there is light literally all of the time which makes this beautiful city even more admirable. On top you can make several interesting excursions to nearby places such as Pushkin where you can find a replica of the famous Amber Room.
