Is truth always scandalising?

Is there really another side to every story, and one more version to every truth? From times immemorial, it has always been about the power of two scenarios and settings -- from things such as 'the two sides of a coin', to 'a glass half-empty and half-full,' etc. Well, while i always believed that there simply could be only two sides to any truth - yours and mine - recently, i read somewhere that there aren't simply two but three sides to it - yours, mine, and the reality - and this has got me thinking.

Can we, at times, be blinded by ourselves, or perhaps by the fact that we just don't want to accept the harsh reality of the opposite person, and start believing the truth to be a lie? Just the way a lie repeated a zillion times begins to feel like the truth, does ignoring the truth make one feel that it may perhaps be a lie!

Also, the concept of cheating in relationships has got me thinking. Is is that the one who is cheating wants to enjoy the best of both (or, perhaps, several) worlds? Or does it stem from the fact that, at times, you're just too scared to confess the truth, as it could to lead to losing the person and the relationship too?

Life and it's weird ways, i'd say. On a lighter note, one of my friends had once sent me a funny text, which read 'Dear Parents, the only reason i lie to you about my boyfriends, etc., is because i care for you and don't want to scandalise you with the truth'. But, well, are things really that funny, and is the truth always so scandalising?
