we must bed their master, not the other way around
Umm?! XD
I don't think there's anything wrong with feeling immediately, just on acting immediately on that immediate feeling without that processing. Like if someone is insulting you (either aggressively or genuinely not realising they're spouting nonsense) it's perfectly okay and valid to feel aggrieved but really not okay to punch them out or insult them back. Or is that covered as well by processing and delaying?
I'm having fun trying to help my kids navigate that actually. After a couple of them had one of their sibling spats, one of the involved demanded if they were just supposed to sit there and take it when the other sibling was being mean and why shouldn't they be mean back. It's still within age appropriate for my kids but it does bug me that there are so many adults that seem thoroughly justified in this thought.
