The poem
When I was a child, I thought, Casually, that solitude Never needed to be sought. Something everybody had, Like nakedness, it lay at hand, Not specially right or specially wrong, A plentiful and obvious thing Not at all hard to understand.
Then, after twenty, it became At once more difficult to get And more desired - though all the same More undesirable; for what You are alone has, to achieve The rank of fact, to be expressed In terms of others, or it's just A compensating make-believe.
Much better stay in company! To love you must have someone else, Giving requires a legatee, Good neighbours need whole parishfuls Of folk to do it on - in short, Our virtues are all social; if, Deprived of solitude, you chafe, It's clear you're not the virtuous sort.
Viciously, then, I lock my door. The gas-fire breathes. The wind outside Ushers in evening rain. Once more Uncontradicting solitude Supports me on its giant palm; And like a sea-anemone Or simple snail, there cautiously Unfolds, emerges, what I am.

Its a great poem, i like how it describes the feeling of being alone. Its such a bitter-sweet feeling. On one hand its very calming and relaxing. On the other hand, if your alone you have almost nothing because all happiness is based on society/being social.
