Humility, and open-ended, progressive way of thinking, feeling and absorbing any walk/s of life. With a degree of sensitivity and transparency.
I'd like to say humility; once more. After having been through severe child abuse (yep, there is such thing as child torture) by my father (biological) - I've never ever objected anyone simply for what they are, yet I am continuously objected for who I am and what I do.
But through this I believe in discovering and "feeling" of humility - the act of lowering oneself first before any ways of extroverted judgment - is something that everyone should practice at least once in their lifetime. They may not gain anything from it, but the experience as well as what we feel out of by simply lowering ourselves to others is unique beyond words.
No, I may not have met as many people simply by way of "numbers/quantity" of what is "socially acceptable".
But dare I know for sure that none in whomever I met through life do inherits similar values as mine.
