I value absolute honesty greatly and actively seek to express myself without resorting to any intentional lies. There are only very few instances where I would even consider intentionally lying to someone about something; when someone elses life or well-being is directly being threatened. Still, even before resorting to lying I would try my hardest to get out of the situtation or resolve it by some other means. These sort of instances usually derive from cultular and societal issues which may have to be resolved before complete honesty can be practiced. For example, I wouldn't have straight out revealed that Anne Frank was hiding in as secret room behind a bookshelf, but I would've still avoided lying if at all plausible.
In more ordinary situations I would never lie intentionally because I see lying as a real problem and always disrespectful towards youself and others. While I would try to deliver hard news as gently as I could I would not lie for anyone just to make things 'easier' for them. I always assume someone is mentally capable of handling me being completely honest with them. It should be noted that being honest in itself has nothing to do with being rude.
Being completely honest (if need be, in an understanding and sympathetic way) is hardly ever the actual cause of harm. Being honest and telling the truth may result in a fight, for example, but it itself is not the cause of the strife. It may act as a catalyst for some discomfort, but there is always some other underlying issue causing the very situation.
Sarcasm is also something that I avoid as I see it as a pararrel to lying. Using sarcasm may not techically be telling a lie, but you would still be expressing yourself in an indirect and often mocking way.
I do not like being lied to. I know other people do lie to themselves, to eachother and to me in a daily basis. I can even theoretically grasp why this is, but what I cannot understand is why lying is considered to be necessary or even, at times, an acceptable or preferable part of our culture. Lying is something we really should look into making as obsolete as possible.
I'm not saying that I truly am always honest. Surely there are times when I tell a lie without completely being aware of it consciously myself, but I will always correct myself If I catch myself ever telling a lie. At the very least I consciously try to avoid lying - as should we all.
