More rolling stones

Back to hospital in Munich for the latest kidney stone removal. This one the follow up to the emergency one a few weeks ago. Not a big deal, the temporary sheath to be removed & then any stones pulled out.  Under full anaesthetic, thank goodness. Should be a short visit.
Took 6:45 am train, a British run one, surprisingly on time. They're under immense pressure as the service they provide here on Southern Germany is constantly making negative headlines. Raining so damp 10 minute walk from Munich Station to the hospital.
Nice two-bedded room, looking onto a courtyard with massive trees & several families of squirrels. They can't quite get to the windows
