Arthur and I were playing soldiers at the weekend. Actually, he was playing, I was taking photos, and doing that not quite playing properly thing that parents tend to do. (Well, I do, Anne is much better at whole-heartedly joining in.)
And I realised how much I envied Arthur's ability to really embrace his game, to dive in, to believe in it and to get into a flow state, really quickly and easily.
I go through life being really pleased with my ironic detachment (carefully cultivated as a teenager) but it stops me having this kind of fun. I've got to get the naive fun back.
