"You can tell me. I won't judge" Thanks, but no thanks.

As a person, I'm not one who trust other people easy. In fact, it is one of the hardest thing to do. I have a uber low tendency to confide in anyone. I don't think it's so much about me not wanting to, but about me being (pre)programmed that way.

Since my pre-teen single-digit age, I had to learn to take matters into my own hands and deal with them on my own. My parents were too drained and exhausted from the issues they had to deal with and were almost impossible to ask for suggestions and advices from. Being the eldest kid in the family doesn't help either. I don't have an older brother or sister to rely on. Instead, I had my younger brother relying on me. So, I grew up making (major) decisions and figuring things out on my own; ranging from learning how to do a ponytail way back in kindergarten, to deciding on what major to take in university and everything you could possibly imagine in between.
(I consider figuring out how to do a French braid on my own in elementary school, sans how-to articles or videos or pointers from anyone, as one of my greatest accomplishments.)

So, you see, I'm not used to confiding and asking for advices, inputs, suggestions and the whole shebang. When I see something I need to figure out, I'll do so quietly. I don't tell anyone anything. Not even my bestest good friends. So when someone who talks to me only on a hi-bye basis suddenly come to me and say:
"Hey! someone tell me that pshshspshshspshshshs. Is it true? You can tell me. I won't judge."
Albeit silently, I would go:
"Rrrrrright........"
Regardless of whether or not that person means well, I am sceptical. Perhaps even more towards someone who throw the I-won't-judge bait.
Even if I really do have anything at all, why would I share it with someone that I barely talk to?

I don't know what makes people think that they can come to anyone and say that they won't judge, and expect that person to immediately trust them and answer their question. Such things require some kind of a special relationship and we all know that more than just mere hi-bye conversations are needed for such a relationship.
That, and also, humans are wired to judge. We actually need a sense of sound judgment for our existence, as an individual and a society.

"I think that food has gone bad, I better not eat it"
Surprise! We judge our food! In fact, according to my humble and personal opinion, or judgment, for that matter, any sort of opinion is a judgment. We do judge daily. We judge so much we'll do them without thinking and without necessarily having the intention to. I, personally, think that it's almost impossible not to judge. But, it's not the judging that matters so much as to how you judge and what you do with your judgment.
We can say, "(S)he's messed up" and then avoid him/her like a disease and/or talk nasty stuff about him/her to most moving objects OR we could extend grace and help him/her out in any possible way (not taking part in spreading it like wildfires is also one form of help)

With all due respect, I humbly plead, please don't use such lines. Especially if you don't mean it and/or the only intention is to squeeze some juice out. When people are confident in you, they will be the ones that look for you to tell you things.
Questions and (false) assurances won't open one's heart to share. Genuineness and sincereness will, and they take time to prove. There's no shortcut to it.
