One of my Communication Skills teachers once taught us all a very valuable lesson in life, which has stuck in my mind for years, oh, so very well -- mainly, b/c I, myself have violated the rule, oh so many times. Anger; whether it's in posting in any forum or in Chat Room or verbally in Life; anger... you must always think, breathe deeply & re-read what you have written/before you speak.....b/c once you hit that "Send" or "O.k, Submit" button in anger/ or once it lifts off your lips....there's no going back!
What is sent in just a slight moment of anger has caused a friendship of years to collapse w/i a matter a seconds/minutes............I've learned the hard way many times.
Chew on that, I do all the time, w/ great regret
