I have learned not to share my experience, strength, and hope with folks who clearly don't want it. To attempt to do so would be a waste of time and an exercise in frustration.
When folks are clearly seeking help, treat me respectfully, and are willing to listen with an open mind, then I will share freely. When these criteria are not met I simply keep my mouth shut. If someone loses out on whatever experience, strength, and hope I can offer from my unique point of view, it's their loss.
I deserve to be treated respectfully; when that doesn't happen, I show respect for myself by choosing not to share and bowing out.
