Act 1
I see children shouting: "Only one bar of chocolate? I want more!"
Adult theoretical particle physicists, instead, are much deeper: "Only three dimensions? I want more!" "Only these symmetries? I want more!" "Only these particles? I want more!" "Only this energy? I want more!"
Act 2
After the answer "Sorry, there is none left.", children say: "You are nasty!"
Adult theoretical particle physicists, instead, are much deeper: "You are stupid!"
Act 3
After that, children get creative in some new direction.
Adult theoretical particle physicists get stubborn and go on. Who is wiser?
