One key difference between the sexes

In his new book Levels of Life, which, among other things, is about the beginnings of photography, Julian Barnes comments on ‘one key difference between the sexes’:

when a couple who had been jointly photographed returned to examine their proofs, the wife always looked first at the portrait of her husband – and so did the husband.

Anything wrong with that?

Barnes continues that ‘most were inevitably disappointed when they finally saw a true image of themselves’. And I can relate to that, too.
