A mother with four children in the 5- to 10-year-old range got on the subway during the evening commute. It wasn't particularly crowded, being a holiday week, so the kids all found spots next to each other, which was next to me. The mom went to sit before she realized they were a seat short, and momentarily looked at me before bracing herself against a pole.
I felt like saying, "I'm sorry, but I'm four months pregnant underneath this winter coat. Otherwise, I would give you my seat." But I didn't say anything, because I hate the idea of pregnancy being an excuse (my nausea was the real reason) or a condition that I should apologize for. Still, I felt uneasy the whole ride because I'm not sure if that seat should have been hers or mine. In the end, I probably should have stood up. Her hands are more full than my uterus.
I guess you could always blame the person sitting on the other end of the kids.
