You’re not really exhausted until the hallucinations start: Droplets of mercury floated in my peripheral vision. A lemon levitated out of the fruit bowl. A streetlight at the corner of State and Garfield laid its long body down on the sidewalk. The cat looked up at me from the corner of my desk, twitched his muzzle, and said, “Libby, Libby, Libby.”

In rugby I find a clan of women who braid their hair tight to their scalps, who have tattoos and girlfriends and are fiercely loyal. They are my comrades on the field. They risk injury for me, and I do the same for them. Since women’s rugby is an underfunded club sport, we fight for field space, wake up early, play on the rocky public fields of Oakland.

It’s February in New York City, and I’m the only one in the family still speaking to my grandmother. That’s not quite true; my father, her son-in-law, will talk to her, too. But he can’t take off from work today, so it’s up to me to get her across town to an urgent hematologist’s appointment.

Irish Mike and I had planned my trip — the “Grand Tour,” we liked to call it — on the floor of a job site.

The pills are about the size of a bing-cherry pit in diameter and are a faint green color, like the eggs of some songbirds. On one side they have a deeply inscribed SZ, on the other, the number 789. They are Ritalin, the ten-milligram kind. Imogene knows them by sight because occasionally patients admitted to the psychiatric ward where she works as a nurse have containers of assorted pills, and she has learned to spot the ones that will get her high.
