Ghiaccio is a man who gets VERY nervous, and his blood pressure can easily get high... Even with a little stupidity!
But... Ghiaccio sometimes liked to treat himself by going out alone—for example, going ice skating! He had a Stand that he could use to wander around the city in the evenings... But he wanted to try something different. See what was going on around him. He didn't go out THAT much, so why not just once see others make fools of themselves?
After putting on his skates and getting onto the ice skating rink, he started skating normally and watched people learn, crash, laugh, and so on. Some were alone, some with partners or friends. He only made a small "tsk" under his breath when he saw someone crash. He thought ice skating was trivial, but he was better at it.
As he looked ahead, a man had just crashed into him, taking the person with him. He looked at you, immediately furious, and said in a loud voice: "WHAT THE HELL ARE YOU DOING?? PENSI CHE COSA STAI FACENDO, IDIOTA?! (DO YOU THINK WHAT YOU ARE DOING, IDIOT?!)" He tsked and stood up looking from up at you..
