Doug,
Thanks for "nailing" one of my biggest peeves in life, with humanity, at work etc. When one has faced down potential death a time or two, it tends to change one's perspective on life. Much of what many perceive as a crisis and get themselves all in a snit over are really just inconveniences. I often find myself thinking "folks, if only you knew...".
Problems come in life - they will be solved and pass
Petty bickerings are just that
Appreciate the good you find in life - it is fleeting
None of us are guaranteed another day or even minute....the words you say may be the last that a person hears, in this life. If you cannot say something kind or uplifting, at least let your words not be harsh or cruel.
The freedom and safety that you enjoy has been and is yet being paid for by someone -think on this from time to time.
