Human beings dressed like sheep

It is the first week of spring; still a bit nippy.
I arrived at the train station to find that a train had just been cancelled due to mechanical problems. There was a mini exodus to the train that I was catching. My train was soon packed.
A few more stops and we were standing back to back; human beings dressed as sheep. Woollens and jackets; it became almost unbearably stuffy.
The half hour ride seemed longer than ever.
I can imagine how sheep feel on packed trains on the way to slaughter.
It was a relief for this sheep when it reached its destination.
Baa baa.
