… that Bratislava is delightful, but not until you’ve had a shower;
… that carrying too heavy a bag detracts from one’s enjoyment of the great art in the Zwinger at Dresden;

In short, to attend to my bodily needs in a timely fashion. And travelling alone meant that I had to take responsibility for all that myself. I had no companion to suggesting that we go to bed, or to decide which café we ate in or what sandwich I wanted. 2018 taught me to take care of myself.
