My neighbor Dorothy stopped me at the bottom of the stairwell on a Tuesday morning, just as I was pulling on my coat for garden club, and said something no mother ever expects to hear.
“Margaret,” she said, lowering her voice, even though the hallway was empty. “Do you know your son comes into your apartment every Monday while you’re out?”
For a second, I thought I had misunderstood her.

Dorothy was seventy-eight, widowed twice, and sharper than most people half her age. She lived across the hall from me in a brick apartment building on Sycamore Avenue, the kind of building with brass mailboxes in the lobby and geraniums in the front planter that somebody was always forgetting to water. She did not gossip in the laundry room. She did not hover at her door. She had lived across from me for eleven years, and in all that time, I had learned one thing about her.
When Dorothy made herself uncomfortable enough to speak, you listened.
