What happened to Day 5?

No internet access.  But our last day in Warsaw was spent happily and involved the post office, the Palace of Culture and Science, lunch in the amazing LOT building, a spontaneous visit to the Applied Maths department of Warsaw University, the most amazing latte I've ever had - Tiger Latte at Coffee Heaven - perfection in the form of spiced, steamy milk, and finally embarking on a train straight out of Anna Karenina, with net curtains, red carpets and potted plants in the compartment - the Warsaw-Minsk Express.
