I can't imagine a parent letting another parent yell at their kid over anything

*blink*

Sorry, I am having a literal moment. Do you mean that you know this is a common thing that happens, but personally given how you feel about your kid, you can't understand how they would do that? Or do you mean that you can't imagine that this happens?

Because I can assure you that it can happen. Easily. Personal anecdotes available upon my failing a saving roll against tmi.
