Giotto's father meets his son's teachers

A true tale about the famous Italian painter Giotto di Bondone:

Giotto’s father wants to know more about his son’s school performance, so he goes to the annual parent-teacher conference. He enters the Italian litterature teacher’s office and says: “H-hi, t-teacherr, I’m Gio-t-t-o’shh fa-ther, is m-my s-shhon d-doing w-well?”. The teacher looks at him with a disgusted face. “What’s wrong with this man? He speaks like somebody whose tongue has been cut off!”, he thinks. Still shocked, the teacher tells the man about Giotto: “I’m sorry, but Giotto is a terrible student. He knows nothing about Italian litterature and during my lessons, I always see him drawing on his desk, paying no attention to me”. Hearing these words, Giotto’s father goes mad and starts uttering: “W-what? T-thish i-issh sshameful! T-tonight I’mm g-gonna t-teach him w-what the word d-dishhipline r-really meanssh!”
So he leaves the room and goes to the math teacher’s office.
“H-hi, t-teacherr, I’m Gio-t-t-o’shh fa-ther, is m-my s-shhon d-doing w-well?, he asks.
The math teacher doesn’t believe his eyes. “How could this man end up speaking like this? I can hardly understand what he says as he keeps spitting all around the office!”, he thinks. Then he answers the man’s question: “Giotto is a disaster, sir. He can barely count to 10 and whenever I look at him, I find him drawing on his desk”. Giotto’s father goes mad again and leaves the office. “T-tonight I’m t-teaching him a l-lesshhon!”, he shouts.
Finally, Giotto’s father reaches the art teacher’s office.
“H-hi, t-teacherr, I’m Gio-t-t-o’shh fa-ther, is m-my s-shhon d-doing w-well?”.
The art teacher is shoked at first. “What happened to this man?”, he thinks. Then he smiles: “You’re a very lucky father, sir! Your son is a genius! He draws like no other. I’m sure he has a bright future ahead of him. Yesterday, for example, he painted a window on my classroom’s wall. Outside the window you could see an amazing landscape wih hills, flowers, birds and even a river! It was so realistic that I tried to look out the window and I hit my head against the wall!”, says the art teacher while pointing at a large patch on his forehead.
Giotto’s father seems to be unimpressed: “W-Well”, he says, “t-that sshhhhon of a b-bitch! It wasshh worshhe f-for me! Two d-days ago he p-painted a pusshhy on the shhtove!”
