A man takes his 7 year old daughter to visit a castle. while they are visiting the
castle, they come accross some stairs that lead to another floor. since the castle is
filled of history and authenticity, the man, amazed by the castle, tells his daughter:
“can you believe that a long time ago, the king, ministers and other important
people used to take these same stairs…” to which the daughter responds: “yes, it’s
so obvious!” the man, a bit confused, asks her: “why do you think it’s that
obvious?” and his daughter responds: “because there weren’t any elevators at their time!”
