怎么说呢？一个人走，不能说是孤独，仅仅是寂寞。觉得无事可做，不能说是孤独，仅仅是无聊。看透社会的阴暗，不能说是孤独，仅仅是超脱。泛泛于大化，不能说是孤独，仅仅是破落。只有体味了无聊，寂寞，超脱，破落。拥有了一种心境，一种宁淡，释然的赤子之心，或许，才能叫孤独吧。

仅仅是我自己的理解，有不同意之处，请谅解。What can I say? A person walks, was not alone, just lonely. Think nothing else to do, can't say loneliness, only is boring. The dark, not through the social loneliness, just beyond that. Broadly YuDaHua, was not alone, just be overthrown. Only appreciate the boring, lonely, detached, be overthrown. Have a state of mind, a rather pale, letting go of pure heart, maybe, can call lonely! Just my own understanding, have disagreed with place, please understanding.
