It's a type of social threat. As in, it threatens our connection to other people. At a very base level, it looks like we're worried that criticism means people don't like us any more and won't let us be part of a group.
We need security that it doesn't indicate an irreparable break with groups we care about being part of. We need to know how to repair it.
You wear guilt
Like shackles on your feet
Like a halo in reverse
I sort of love the image of a halo, a thing that's elevating and around your head, where you think, sliding down to be around your feet, preventing you from acting.
1) We're going to screw up.
2) We're going to get criticized for it.
3) We're going to feel embarrassment in response.
4) If we accept/own that embarrassment, we're going to feel guilt.
5) We don't want that guilt to turn into shame.
1) You're going to screw up without meaning to, or even realizing that you screwed up.
2) At some point, you're going to become aware that you screwed up.
3) Because you're basically a decent person, you're going to feel bad that you screwed up.
4) Now what?
The end.
