Sorry, guess I didn't phrase that very well.
I didn't mean you never tell the truth, or "tell like it is". I just meant some people use it as an excuse to say what they say in a nasty way. That is what I think is unnecessary.
I don't imagine a doctor will just walk in and blurt out, "You're gonna die." I suspect they will pick their words very carefully as they tell you the truth, and probably try and do it in as easy, kind, thoughtful and respectful way as possible. Telling it like it is, but tactfully- in a respectful way, is simply making an effort to tell the truth without bashing someone over the head with it. There's a reason why Mary Poppins said a spoonful of sugar helps the medicine go down.
Don't know if I'm explaining myself any better or not. Maybe I'm being too tactful?
