No smoking almost everywhere. (people used to smoke in restaurants and airplanes and stores).
Brewed decalf coffee (although I am coming to question the wisdom of decalf anything, still powdered nescafe just sucks and has little relationship to any flavored beverage).
That I can lecture in comfortable pants and flat shoes. I am lecturing this morning, and was remembering when I first started teaching, that one (if one was a woman) wore heels and stockings and a Nice Outfit. Men wore ties and suit coats. I am guessing men's shoes weren't quite so uncomfortable, but they sure as heck weren't sneakers. And, students frequently judged on how one looked. Not that student evaluations were taken seriously in those days (yet another sub-improvement in the world).
No, not everything is better. And right now many things seem worse, and that makes this list seem a little trivial. There are many things wrong in our world. We need to work towards fixing them. But, sometimes, right now for me, taking a moment to appreciate the little things makes dealing with The Big Things easier. Amongst the (to the world, but not me) little things: I am well loved by several people, they forgive me for my screw-ups, and will hold me when I feel the world is really dark. Thank you, my friends and lovers. Thank you.
