you know...nothing says you can't say what you want to say NOW...if you say what you want or need to say in a diplomatic manner...it can be said.
I learned that there is power in my own words and I AM ALLOWED to express my opinions. I am not a horribly wicked person (I mean I CAN be but I am not usually one) and so when I have been treated like crap, it has been very important for me to acknowledge that and say it isn't OK instead of just sucking it up.
I reply in an even tone and a diplomatic manner that what the person is doing or saying is not appropriate and it is not something I deserve and they can treat me with respect and if they don't, I will chose to walk away and not take their crap.
