In the past, when children were young, they always clamored to play outside, especially in crowded places. They were most interested in watching some cartoon characters and some adult performances disguised as clowns.
The reason for the current epidemic is that they always stay at home, and they are used to it. They don't like to quarrel about going out to play as before. Now the streets and shopping places outside are not as busy as before, and they have become very lonely. This is all caused by the epidemic.
