Day of two halves

An interesting art installation , inside handmade pods.
Each pod represented a different city around the world.
In each pod an atmosphere was created to show air quality and pollution.
The clear clean air of Norway to the humid polluted air of Delhi.It really felt and smelt very different .
The second half happened in the way home. I walked into a metal barrier at head height! How did I not see it!!I bounced off, lost my balance and fell backwards cutting the back of my head on the road. The journey back on the train was spent mopping up blood.. and feeling rather miserable .
Tea , TCP and parecatamol..
