Life remains a blessing Although you cannot bless. - W. H. Auden

Normally, when one passes someone on the street who is in pain, one either tries to help him, or one simply looks the other way. With a photo there's no human decision; you're not there; you can't turn away; you simply gape. It's a form of voyeurism.

And none will hear the postman’s knock
Without a quickening of the heart.
For who can bear to feel himself forgotten?

So long as we think of it objectively, time is Fate or Chance, the factor in our lives for which we are not responsible, and about which we can do nothing; but when we begin to think of it subjectively, we feel responsible for our time, and the notion of punctuality arises.
