Nurse & jockey

Started antenatal classes today. This totally weird painting of a nurse & jockey (not the place in Tipp) was hanging on the wall!
Found the class irritating!?
Wanted to be back in the one I did Saturday.
Next one better be less rushed or there'll be trouble.
Suppose reiterates the fact that it's a busy hospital and we're all just numbers.
Get ready for the conveyer belt.
Maybe that's why the nurse needs the jockey to help her speed around the hospital?
No sign of the horse though. Hmm ;-)
