Walking along Adalberstrasse direction Kottbusser Tor, from friend K to my home, I cross Waldemarstrasse and I suddenly remember the ancient Berlin winter smell: Kohleheizung! Briketts! Union and Rekord! Coal heating, 30 years ago was pretty common then, briquettes called Union and Rekord, one East one West as far as I remember … which was better? Forgot … I am sure we used the cheaper ones! I’ve lived here for so long, I love my Berlin.
