This morning a request for help reached me via eMail:
Hey Andrea, this strange year was sweetened a lot by finding a number of pieces of graffiti, depicting all the same – a runny nose. I would like to thank the artist(s), who have made my lonesome walkings a bit more pleasent. The noses appear everywhere downtown Bochum. 27 of them I have found so far and I would very much like to know, who is responsible for those sniffy noses.
