Avoid shopping and the U-Bahn at all costs!
This one is pretty simple – Avoid the shops and the U-Bahn in December as much as you can if you want to keep your faith in the good of humanity intact. People (and tourists) in their big jackets squeezing in on the U-Bahn, waiting an hour in line in shops. Just give up already. We’re sure that’s not what the big man upstairs had in mind when he thought up Christmas.
