Anyone else's parents generally tactless and socially ungraceful people?
I think it's a big underrated part of what makes them such incapable parents sometimes.
They're just... tactless people. They don't know how to set the tone of a conversation or be the leading figure in creating a safe, fun environment. They don't know how to "command the crowd" of the family. That's why their attempts at connection fall flat and family vacations are so... dang... boring.
Instead they go around socially oblivious on how to say things softly or palatably without realizing how their words are coming across.
One thing I've learned is huge is tone. Being able to say things a certain way that communicates lovingly but effectively. Like an indirect "Hey, we're all ready to go soon" versus a brisk and confrontational "Are you ready yet?" Both communicate the message that everyone is waiting for you but one leaves the conversation open and inviting while the other is accusatory.
But our parents won't understand those nuances and so their when their words are abrasive or dismissive and it inevitably upsets the child, they don't understand what has possibly gone wrong. Because they don't understand tone. To them, words are just a tool for strict practical communication and not a means by which we indirectly communicate intent, subtly vibe out the other person's feelings, and invite others into our inner worlds.
