Herbs, dear me, was there something odd in the ice cream he had? Or do you think he's a bit antsy about going back to school?
Re: antisocial - I'm not sure who is more so, dh or me. Yesterday, the singer from dh's band wanted us to go with her and a few other people to see a band at a local pub - it was a last-minute thing and I'd just come back from being in town with the dcs, so said no. Dh said he didn't want to go if I wasn't going, so that was that. Apart from a brief coffee with a neighbour and her dcs (at her suggestion), I've not seen anyone other than immediate family for the last 2 weeks (not counting extended family on Xmas Day and Boxing Day) and I'm perfectly happy with that. I like a lot of space. Dh, dd and I are all the same, but ds not so much. He is more of an extrovert type who likes company all the time.
Sympathies to those with worries about their dc's diets. Ds would eat to excess all the time if he were allowed, so he is not allowed (cf: puking after being left unsupervised in the midst of vast numbers of cupcakes). I am currently debating putting a lock on the larder door. TBH, it might also help his father.
I am currently trying to be gently supportive to help dd get herself halfway ready for going back to school tomorrow. I have just looked at the school website and see that the deadline for 6th form applications is a week on Wednesday and I'm pretty sure dd has lost her application form. She will probably make an enormous song and dance about having to request another one, i.e. she will expect me to sort it out. Ho hum.
I had to spend some time drafting and redrafting an email to a cousin this afternoon, after receiving a raging and bitter communication from said cousin. He was diagnosed with lymphoma a few months after dh was diagnosed with cancer and he had to have horrid chemo etc. He decided he couldn't cope on his own and moved back in with his parents (he is 49, single, and his parents are nearly 80) during treatment. He sent graphic "newsletter" updates about his treatment and state of health to everyone in his address book every couple of weeks. TBH, much as I am fond of him, I found his constant "updates" really wearing, especially as we didn't have the easiest of years last year ourselves, one way and another. Dh was the polar opposite and told no one about his cancer and treatment. OK, cousin's chemo was very nasty, but lots of other people in a similar situation would not have the support he had, i.e. free food, accommodation, taxi service and a laundry slave for 6 months. He has had good scans and things are looking as good as they can do at this stage, but he is full of fury that hardly anyone went to see him whilst he was at his parents (in Surrey, so not near here), response to his newsletter was "poor" 
and in a particular rage with me because I didn't call him when he "could have died". I never call anyone, aside from my mother (and that's because I have to), which he well knows. Also, he wasn't close to death at any point last year. And when cousin calls me, he blithers on for up to 2 hours sometimes, usually moaning about the way some other relative slighted him 30 years ago, which is exactly why I don't call him. Also, he has turned into one of those people who "doesn't do Christmas" - fair enough, except that he requested that no one send him any cards, presents or invite him to any Christmas gatherings, but now is in a grump because no one contacted him.
Gah.
