DH conversation

I would discuss the homework issue with the parents, not your DH, then it would be their guidelines.

You are not being unreasonable.

I queried a woman gently once about her repeat stories.
She knew and agreed that she was doing it.

My husband can be a bit like that , I'm selective now ref conversation with him . I usually know which way it's going to go . Luckily I have 3 sisters to talk too

DH never says I expect I’ve told you this wish he would then I jump in and say yes you have 🫠
I’m sorry valdali that sounds very difficult, as he always been the same ?

I'm grateful when DH does this as most the time he's monosyllabic or talks to the dog - to be honoured with a story, even if I've heard it 20 times, makes me happy...

I had a colleague, male, who would repeat the same stories over and over again, usually starting with 'I expect I have told you this before'; we would agree, even repeating the content; he would say yes, that's right, then go through the whole story again. Now on a committee with him, still happening.
Nothing you can do.
