This is what I did with my kid… after the divorce. Before the divorce she did the “stay at the table till you’ve cleared the plate”, etc.

I wasn’t raised that way, and I didn’t agree with it, but she insisted.

I’m glad I got divorced, it was such a relief. I’m probably not supposed to admit that out loud, but it’s true. To be clear, this wasn’t the reason we got divorced, it just irked me.
