THE POINT OF NO RETURN

Took the lift from halfway up.
I heard voices and the note from down below and hoped it was people getting out not in.
On the floor in the corner of the lift when it arrived and the door opened I saw an empty can of Rubicon soft drink, orange flavour if its colour was anything to go by.
The Rubicon was a small river in the north of Italy which generals were forbidden to cross at the head of an army. It was an attempt to protect the republic of Rome from an internal military threat. Caeser did it and by doing so understood he’d sealed a fate.
“Crossing the rubicon” is the point of no return, when you’ve done something you can’t undo, when it’s too late.
