Why are the little spirits always so thin?

Netizens said that when I used to run a bar, a few little spirits would come by.
When they first came to apply, each one was heavily made up, all wearing pretty dresses.
They were wearing blackened slippers and cheap makeup.
Seeing them pitiful, I invited them to eat. The girl who could eat five bowls of rice in her life, finished all the soup.
Before, I was in a bad mood and was daydreaming in the square at midnight.
I met a little spirit who came over to find me for a smoke.
I gave her a cigarette, and after a while, she came back to ask if I was in a bad mood.
Then she talked nonstop for a long time just to make me feel better.
When I left later, I left the cigarette for her.
The next day, I passed by the square and saw her again; she hadn’t eaten all day.
I treated her to a barbecue, and she even wanted to go home with me.
Some little spirits are actually just innocent children.
