Hint on what Otavo is about: (a limerick)
There was a young man who said: "Damn!
It seems to me that I am
An engine which moves
On pre-determinate grooves
I'm not even a bus; I'm a tram!"
The young fellow then thought, Ã¢â‚¬Å“No,
It is not necessarily so,
The argument fails,
I can lay my own rails,
And go where I want to go."
