How to describe Anna in Notting Hill as silly?

A good romance movie feels like a weekend in autumn. I woke up naturally, the weather was neither hot nor cold, the sun slipped in and lightly sprinkled on the pink blue sheets. Opening the window, the maple leaves flying in the trees outside were in full bloom. Your boyfriend sends you a message and says: "Zhutou, get up quickly, let's go eat spicy hot pot for lunch." "Notting Hill" is just such a movie.

In order to avoid being disturbed, Anna used to register under a pseudonym she made up at random when she went out to stay in a hotel. The first time she went to Notting Hill to film, Anna checked into the Retiro Hotel under the name "Flynn Stone". When she called William, William happened to be away. Anna had no choice but to ask William's roommate Spike to tell William to call her at the Regal Hotel.

Spike remembered that a girl named "Anna" was looking for William, but he forgot what name Anna used to check into the hotel. In order to win the sympathy of the hotel receptionist, William said: "Anna did tell us her check-in name, but my roommate was so stupid that there was no way he could remember two names at the same time.

He's really stupid, you know? You can think of him as the stupidest person you understand, and then multiply it by 2..."
