Mrs WBill was a bit peevish about it, mostly because "Her mother-in-law knew more about her underwear" than I did. But otherwise, she was very grateful....and correctly so.
If my kid hated me because I'm a "Rethuglican", I'd likely be less forgiving than the Mom in your story. But, I'd also excoriate myself and wonder where I went so terribly wrong to have my child hate me for something as trivial as petty politics.
to a real leftist, everything is politics. everything.
And you may think that you'd be less forgiving but if your kid was in pain and needed help you'd be there. I'm not certain the reverse would be true.
