I sit alone, outside. On a bench. Alone in a park. I sit on a wooden bench which is placed alongside a hilltop path, looking toward a brick made school, which has a playground on one side of it, and on the other side, a fairly large amount of pavement and green fielding that the kids can play on. I look to my right, and I see another path (well, the same path as the one I am sitting alongside) at the bottom of the hill. Walking on the path slowly is a small man, although old in age. He walks to a bench alongside the path at the bottom of the hill and he sits. It's 11 o'clock A.M. He sits on the wooden bench, alone, outside in a park. At first he sits uptight, and then he puts his head down as if to experience utter failure. He's pondering his life. Just sitting there thinking. On my bench I sit and I watch hime pondering his life. Such dysphoria comes from watching him, just sitting there with his head down thinking those depressive thoughts. Soon after he gets up off the dark wooden bench and continues to walk down the path, which leads to the school. I sit on my bench on the hilltop. Down under the sky and the clouds is the green field which is outlined by the path the old man is walking down. He continues... going further and further... getting smaller and smaller... Eventually I get up off the dark wodden bench and walk along the path back home. I look back to the man, but he's gone. I keep walking... going further and further... getting smaller and smaller...walking in eternity... And I can't help but think that that one old man sitting on the bench was thinking the exact same thoughts as me.
dysphoria, n. -- a sense of ill-being and dissatisfaction. Interesting, but where are you going with this little scene, now that your readers are feeling dysphoric? Also: "A small man, although old in age...". The word 'although' implies some contrary meaning between the two elements in the sentence. There is nothing contrary between 'small' and 'old'. "Old in age" might be better phrased as "Old".
