Well indeed, Beachy. I had assumed he was coming to the concert, so had been gaily filling him in on the probably horrors in store. So when DS said to him 'are you coming daddy' and he said 'no, I'm tired and it's not my thing' it was a surprise.
I have cut him slack re bereavement, and am imagining this might be why he is so particularly monosyllabic at the moment, but he has form. He sulked all the way through a three-day stay at CenterParcs with friends, as it 'wasn't his thing', refuses to take DS swimming (ditto), go camping (ditto), etc.
Re driving, it has driven me mental in the past, though less so now as we - or indeed, I - don't have to flog out to see his parents every couple of weeks down the M4. But it is I who has to do the choir ferrying. It is doable by train, and pretty quick, but DP isn't back from work in time. Though I dare say he could be.
Very irritatingly, I have had to cede the moral high ground. After lunch - at Caminos! - DS and I got the train home, while DP went to do some Good Works with his charity. When I got home I realised I'd left my keys inside, so had to summon him home. I am thus once more in the dog house, and am having to be Bright and Cheery.
