This is a the story of a 5 years old son, who, after watching a story of an Emperor on TV, said to his mother:
"Mum, I also want 7 wives, one will cook for me, one will read for me, one will go for walk with me, one will sing for me, one can bath me...."
Mum smiled and said: "Then night time I don't have to accompany you to sleep."
After some thought, son said: "Not possible, I still want to sleep with you mummy!"
Moms eyes fill up with tears of happiness: "My sweet son!"
"Then who will sleep with your 7 wives?"
"Let them sleep with daddy!"
Dads eyes fill up with tears of happiness. "My sweet son!"
