DH works full time in agriculture and also looks after cows on his parents farm (he does that after work and on the weekends). During the week he'll finish is full time job 6ish then goes to his parents farm to sort the cows out, then comes home about 7:30pm. I'm used to this, I understand that he needs to do this and I think it's amazing that he effectively has both a full time and part time jobs.
Today, he worked until midday then called in sick due to a panic attack. Instead of going home, he went to his parents to sort out the cows, so far I'm in agreement that this makes sense to do. However, when I ask what time is his coming home (cos I'm thinking yay he'll be home earlier tonight and we can spend quality time taking about how he's feeling and what happened in work), he replied "hopefully not too late" which generally means 7-7:30pm
AIBU to expect that instead of coming home at 7:30pm he'll actually come home maybe sometime closer to 6pm at the latest? He's had from midday to sort out the cows and see his family. He didn't get home until 9:30pm last night due to a cow emergency (which I understand). I struggle to find the words to respond to him other than "yeah, I really hope you won't be too late" which comes out really sarcastic.
