Modi refers PM as ‘Moun’ Mohan Singh ?

Moun in Hindi means ‘Silent’ and thats how Gujarat CM prefers to address PM Manmohan Singh.No matter,what Mr Modi says about the PM,never has Manmohan Singh responded back in agitation,not only against Modi but anyone who has ever criticized Dr Singh for remaining speechless on all major issues related to the country.

Should he be appreciated for never involving himself in any verbal conflicts or be criticized that he genuinely has no answers to support the ills of his govt?  🙁
