Growing up, I was never allowed to “talk back” to my parents. Eventually I started caring less about what they said and learned to endure their verbal abuse. Even with other people, my default response to any form of insults and disrespect is to emotionally shut down and stay silent, which leads to others seeing this as an invitation to walk all over me.
In fact, I’ve grown so numb to this kind of thing that I don’t realize that I’m being disrespected until I think back about it much later, then I start beating myself up for not saying anything.
