I cut folks who are crying huge amounts of slack, because who knows what really is going on in their lives?
And perhaps because decades ago, I had the worst flight of my life. My two late-middle aged parents and myself in F, and my 20 year old sister's body in the cargo hold. Dead suddenly after an unknown til then cerabral arterio-venous malformation ruptured. We weren't crying, but the three of us looked like we had slammed into a brick wall at high speed, I'm sure.
I do try to remember that some folks on every flight may have just come from a human tragedy or on their way to one.
