This morning, I boarded the front car of a fairly crowded train and moved toward the seats. I hadn't even noticed that I entered through the door nearest the conductor, but he noticed me. Before I could even get in front of the seats, the conductor leaned over, tapped a seated passenger on the shoulder and asked the guy to get up for me. He was more than happy to do so and even helped make a pathway for me to get to the seat easily. Both men smiled kindly and waved off my thank you as though I shouldn't have even said it.
