flatterers praising a person too much
A flatterer can never be a true friend because a flatterer always praises for everything the person they flatter does or says to get some personal benefit from him; whereas, a true friend condemns when his friend does anything wrong or even silly.
The worst kind of flatterers are the political flatterers who, by their flattery, create a make-believe world around a politician, hiding all the lapses and highlighting only the imaginary virtues.
The media in general is hailed for its impartial and truth-seeking efforts to bring to light the good and the bad of everything, but some critics say that there are flatterers in the media who show only the bright side of an issue if it favours them!
Great people, like Mahatma Gandhi of India and Winston Churchill of the Uk, are not susceptible to flattery; they know how to avoid flatterers who cajole favours by flattering those who are in power.
