Which is worse?

Emotions... abstract stuff, aren't they?
As aforementioned, do people really understand the meaning of "I love you" when it comes out of our mouth?
Even if they do, do they really mean it? Well, others will never find out, will they?

Humans are seriously truly scary creatures.
We have the gift of conscious thought, yet also the discretion to hide.
We have the ability to trust, yet also the skill to lie.
We have the heart to love, yet also the probable intent to destroy.
Disastrous concoction isn't it?

"You'll never know what I know unless I tell you what I know truthfully."

Thats my favourite quote (from yours sincerely) that summarises human connections.
What people don't say, we will never know.
Even for what people say, we can never know the truth behind the words with absolute certainty.
We might assume that people would be truthful when talking about grievous issues,
especially those that of the utmost importance to oneself.
Yet, does this assumption stand without fail? Is it always reciprocated?

We all have a different set of moral and value judgments, with regards to different matters that pertain to us.
We have a uniquely calibrated ruler to measure the importance of issues ;
to some it may be the difference between heaven and hell, to others it may be as trivial as a game, a pastime.
How then, can the aforementioned assumption stand,
when we don't know how much importance the other party puts into the issue and the thoughts they are harboring?

When it comes to conversations, some parties might have an inherent (or artificial) high ground as compared to others.
Such is the ground that those with overarching knowledge holds.
They have the power to incept, to plant ideas in the minds of other parties which may not be true.
They have the power to hide, to only show certain sides of themselves and certain ideas they have.
They have the power to exploit the other parties, to manipulate and gain almost total control of their relationship.
Then of course, they have the power to tear apart their relationship with ease.
Terrible...

...Especially if it comes to the matters of the heart...
