The suburbs have a way of giving you the impression that you know everything there is to know about your surroundings, even while you don’t. For three years, I lived on a peaceful, tree-lined cul-de-sac where the most exciting thing was generally a particularly obstinate lawnmower or a missed trash pickup. Three doors down, in a home that appeared to be frozen in 1974, lived my neighbor, Mrs. Henderson. She was eighty-two years old, a skinny woman with translucent skin and eyes that seemed to be looking for something she had lost decades before. Our interaction was limited to exchanging courteous nods and discussing the weather.

At the time, it didn’t seem like a huge deal. The humidity was unbearably high on this Tuesday afternoon. Mrs. Henderson’s actions were painful and stiff as she pulled her rusting vehicle into her driveway. Her hands were shaking as she struggled to hold onto multiple supermarket bags that were overflowing. With each step, her breath caught in her throat. I didn’t think twice; I dropped my mail on my porch and walked over. Packed with hefty glass jars and canned goods, the bags were surprisingly weighty. I took them from her, gave her a supportive arm, and guided her through her dimly lighted foyer and up the steep front stairs.

Lavender and stale air pervaded the house. She thanked me several times with an enthusiasm that seemed a little out of proportion to the work, and her wrinkled face crinkled like parchment paper. For a brief moment, I was struck by how immaculately clean her home was—no dust, no clutter, simply a sterile, silent museum of a life—when she insisted that I put the bags on her kitchen counter. I didn’t stay. I waved at her, made my way back to my own home, and spent the rest of the evening feeling the tiny, comforting glow that results from a modest act of neighborly generosity.
