One Sunday a short time ago, I was on the local train from New Haven, Conn, to New York City. The train was crowded, and the only pair of seats together were across from me facing backward. Two girls got on at Stamford, Conn.
“These are the only seats together. Our mom is up front,” they told me.
“Sit down, please,” I said and removed my copy of The New York Times from the seat across from me to give them room. They began playing a word game, and I noticed that the older sister was unusually caring and considerate of the younger. She even let her kid sister win a few.
