Your high school senior's BFF attends a college in a city 1.5 hours away by train. Let's say this is a big city, like NYC, Boston, LA, Dallas, Chicago, etc. Your kid wants to take the train to meet the friend, who will greet and return the kid at the train station. Yes? No? Does it matter if this is a boy or a girl? I've already given my decision, but I admit I thought twice about what I said.
