Yes, the word NO. As a kid, I wasn't allowed to use it. As an adult, finally finding my way to help...... finding my way to people who didn't have a problem with somebody (-ME-) saying No..... Golly, the mere concept of sticking up for myself would put me in a cold sweat with the shakes. As a kid, sticking up for myself nearly got me killed. Repeatedly. Dad was a booger. From a very young age.
It's still hard for me to get "No" out my mouth, but my body is very good at walking away. Whatever peels yer potatoes, ya know?
