Only sad if she was junior to you.
We got a lot of tragedy in the world--disease, accidents, and some just darn bad luck. Meth addiction, however nasty, isn't one of those things that sneaks up and shows up on a recurrent physical or an MRI. We are blessed in this world with getting to make some choices, and drugs...especially meth...is a horrible choice. Those educated enough to fly DC-8s around the world were probably aware of some of the downside risks.
Drugs do destroy lives. But unlike cancer, furloughs, accidents, or being a victim of crime, drugs don't come out of the dark and sneak up on us. We abuse them willfully.
Sorry if I'm not a ray of sunshine today. Three friends killed in plane crashes in the last month, and another little gal I know killed in a car wreck. I don't have enough tears or sadness to share with junkies today...
