Holier than thou people

I cannot stand holier than thou people and especially those who believe they have all the answers and say so - publicly. Some even make it sound as though they are installing a blessing on you.
Not only that, their words give the impression that life is perfect for them, when it often isn't.
Be honest. If you want to speak to the world - tell it as it is, warts and all - or don't publish your words to the world in an attempt to give a good impression of yourself.
And to quote dear old Kenny Everett I mean that 'in the nicest possible way'.
