Those pictures that people post, with a grinning child in front of all their birthday presents, carefully arranged - what's that about?
A) Look how lovable Harry is, in this bizarre materialistic world where stuff = love

C) We spent loads of money on Harry, which makes us better parents than you
D) Something else, that I'm too much of a cantankerous miserablist to get?
