When I was standing on platform No.5 in Osaka station, my father said to me "Look at the man over there! He has a doll instead of baby. It seems strange."
As he said, the man held the doll with his face full of smile. It was creepy.
But, I can't laugh at him. If I can't get married to a female, I won't have a child and will have to imitate his behavior. The possibility remains as long as I live without a sweetheart.
