Half full, half empty just depends how one interprets it!! Not saying sadness is only definition of darkness or evil just a mix of thoughts and ways that makes you different then most others. Some people are happy ones, walk around with the sun shining brightly all the time. Then theirs others who have the mix of up and downs. Then there is my type, one who shows happiness in a false sense, feels numb almost all the time. No fluctuation of feelings that make others feel good I guess. The dark is more of a part that keeps what others call a good place away from us. No matter what we experienced in our lives. I notice that I laugh most of the time because that's what is expected (so fake). Smile because that what I am supposed to do at certain moments. Truth is the darkness of thoughts consume me, I allow myself to stay trapped in what some may call stupid. For me it's more like a part of me, one that I am so accustom to that its like breathing. Yes somethings I need to work on (like MOST of us here). Just haven't been able to do that part yet.
