No room to sit. The mother remained standing in the aisle while the girl herded the little boy between two facing rows of seats and took up position near the window, right in front of me.
Heavily barred, it was safe for the little boy. Still, she told him sternly to keep his hands on the sill. He complied. She stood behind him, protective, alert, skinny arms holding on to the window bars on either side of her charge. I smiled to see this elder sister attitude, something that comes easy to me, or did, when my brother wasn't a 6-foot tall adult. She looked at me out of the corner of her eye, saw my smile, and shuffled closer to her brother.
He mumbled something to her. She called out to her mother, was handed the water bottle, and opened it carefully, the fat cap unwieldy in her small, bony hands. She helped him drink, tilting his head back enough so he wouldn't spill it on himself. Done, the bottle was passed back to the mother.
Our train passed another train. She pointed it out to him and they started counting carriages. When he raised his hand to point and count, she firmly pushed his hand back down and brought her elbows closer to his shoulders, just in case he tried again.
He was content, counting carriages, watching the tracks from below his long eyelashes as he stood between his Didi's knees, shielded by her thin body.
When I got up to leave, she gently nudged him to the seat, and rushed to take up position so he could sit on her meagre lap.
On a day when people make huge, expensive gestures of love, this struck me as a wordless love, taken for granted by both parties - a little indestructible world oblivious to the world-weary crowd around it.
