I think 'bout thodi khushi thode gham, that we should not blame manshuk or sneha. its the real fact of indian life,though manshuk n sneha r overacted . In indian family , munshuk role is played by mother-in-law. She is the one how praises her son and thinks bahu minor,n this is the fact.
Then also family move smoothly (though bahu r not treated well). the day changes when bahu like sneha(not fully like sneha)enter to house. I m dam sure each indian house have one bahu like senha.She comes and everything change. bahus starts thinking 'bout there right. They start opening there mouth .
Still i m not going to blame completely sneha type bahu,because fire already exists in all bahus heart it only need to light up.
AND then family starts losing peace
I dont now whom to blame. bahu or saas or pati or sasur.
