I am finally old enough to start understanding certain things that I used to think I understood. The line about those not knowing history being doomed to repeat it, for example. I've made too many of the same mistakes more than once because of my failure to process them properly. That's not much to offer by way of wisdom. As to comfort, I have even less.
So I simply wish that the people for whom this day is especially difficult find some small bit of peace. I will continue trying to make myself worthy of the sacrifices others have made on my behalf by leaving things better than I found them, by showing gratitude for each bit of each day, and by remembering with an eye toward not repeating the past.
Peace on Earth, good will to all.
