Back to London

I travelled again to one of my most favourite cities and this time i went there on my own, for the first time, C. alone in London. As usual i was super nervous beforehand and planned it with military precision.
Booking the flight and the hotel was the easiest part. As i was taking the same late flight as last year i wanted to make sure again to already have the tickets for the Stansted Express train to not lose time at the ticket machine. I wanted to order them from directly from their website and then came across my first obstacle. When i wanted to pay them with my credit card there was some pop up window which informed me about 3 D Secure. It turned out to be a payment system which is supposed to add extra security in money transactions. Well, it was so damn secure that i personally couldn't buy the tickets with my credit card. I did get in touch with my bank and the guy explained a lot of things to me of which i only understood very little
