Imagine this: you’ve been assigned “dessert” for Thanksgiving dinner. You ask around and get a recommendation for a good fall pie (Thanks, Michelle!). You send the recipe to your mom so she can have all the ingredients ready for you when you get to the house. You should have plenty of time – the train gets in at 8:15am and guests don’t arrive until 11am. And then, the night before Thanksgiving, you double check the train schedule… And the train doesn’t leave Boston until 8:30am.
