"Are you sick?" 

Trying out appliances at the department stores.

Playing games at the arcade.

Tasting some food from every food cart.

Watching a children's movie at the cinema.

Discovering where he can buy Spam, a food he falls in love with.

There were a lot more things Christopher experienced for the first time with the help of Berto. He never thought that in one building, he could be entertained so much that he didn't notice the time passing.
