When things linger on my to-do lists for weeks and weeks (or months and months), there’s always a good reason, and that reason is mostly fear.

That’s gallows humor for “euthanize my constant companion, who probably should have been put down a long time ago if this human mother of hers weren’t such a scaredy crybaby.” This cat, you guys. . . .
