I do want S2 to attend his cousin's party. I just think that getting him there is not my responsibility. In fact, that's a wife job. And I sure ain't that anymore. Not to mention the indignity of being treated like a chauffeur when I would have been an invited guest if circumstances were different. I feel that it's insensitive and entitled on their part. They are welcome to pick him up earlier or whenever suits them.
Not sure what time the party starts, but X's usual pickup time is 8am. I can't imagine the party happening that early. SIL has a husband to help her with party prep. FIL or MIL could stay behind if extra hands were really needed. I only get one day a fortnight off from parenting and those 9 hours go fast. And I'm staring down the barrel of four weeks without a break.
I know I don't need to justify my right to say no. Still working on that, I guess.
In other news, I spent a few hours at the hospital with S2 yesterday. He's had a chesty cough for the past week and the doctor wanted him checked for bronchitis, pneumonia and of course COVID. So they put us in an isolation room while they performed various tests (the little guy did so well). Once we were cleared for (just a nasty viral infection) I informed X of the situation via text and said I'd update him once the COVID test result came in.
