How can I explain the powers of the Prmie Minister Vs. The President of India to a 10-year-old?

I will let you know the way my father explained it to me:
President is Papa

• Official head of the Family
• No internal powers but all internal actions are taken in the name of Papa
• He is to maintain Foreign Affairs
• Papa can only act on aid and advise of mummy
• Mostly act as a Stamp
• Have discretionary powers as he can hold decision or delay any particular topic.
• All the children file mercy petitions to PAPA

Mummy is Prime Minister

• Actual head of the family.
• All finance related matters are approved by mummy.
• All the family related matters are planned and approved by Mummy.

Hope it helps. :)
Cheers!
