I’m always really excited to talk to my parents especially my mom so all of my techniques go right out the window lol but she doesn’t mind she’s very patient with me out of all my siblings even now at 25. I’m not sure what causes you to block more when speaking to your parents but with me it’s just simply wanting to have a conversation. It’s not easy but if you can remember try pausing and taking a few deep breaths think about what you wanna say and then slow and steady speak it helps me a lot more than I realize :)
