Questions about education
Many people have a habit of asking questions related to education to the guests who come home. We ask them how far they have studied.
In today's time, everyone shows great interest in asking questions related to income, but you should not ask any questions about the guests who come home. He may feel embarrassed by this.
If a guest comes to your house, never ask him about caste, religion, or gotra. This can also spoil your relationship.
