Another planet?

Radiotherapy went well and quickly as usual these days,despite me arriving early following yesterday's foul-up. They are a great group of people.  The consultation went well in a bizaar way . I asked if chemo would end the same time as radio. The answer was he could not say. I then asked when it was likely to end. The answer was he could not say.  

I then stupidly asked how a decision will be made to stop chemo and what criteria would be necessary? The asst oncologist merely licked his index finger and held it in the air. For non-UK residents this sign means "Christ knows" and not the driving signal meaning "swivel on that".  All informative stuff, eh?

We left wondering who was on another planet, him or us. The jury is out.
