More than one cause for secondary mourning

I've been thinking a lot about the disasters in China and Myanmar, all the people suffering, all the places in the world that people I will never meet are suffering. And my sister-in-law, who I love, just found out her breast cancer is back after three years. There is always sadness somewhere - somebody facing something hard, life shattering. Keeping my balance, being able to work, laugh, enjoy a good book, rest, in the midst of all the suffering - doing enough to make enough of a difference, letting it be enough - stepping back, staying centered. Quite a trick.
