Where to Call Home

When I was a child, my home was a happy family of three, eating three meals a day; When I was in school, my home was a class and a dormitory; After work, my home is a small house with an area of several tens of square meters. The snail's home is its small shell, let it go and be content with whatever happens; The home of animals is their deep mountains and old forests, and the vast sea and sky; Parasites also have homes, and their homes are the resources they continuously draw from their hosts. Does everyone have a home? Maybe. Some people's homes are very big, as big as the whole world; Some people's homes are so small that a heart as big as a fist cannot fit inside them. Throughout the ages, the protagonists have been beautiful. If one day, the protagonist turns into a selfish, impulsive, lazy, negative, fragile and glass-hearted person, will anyone still like him?
