So, here's what we're going to do. We're going to pretend that you're coming for a visit, and I'll take you through everything we'd do during your stay: Saturday, Sunday, and Monday.
So pack up your little pretend suitcase, and bring your pretend flight snacks, because your plane arrives at 9:30 tonight. Pack summery clothes, because it's perfect early summer weather here, though pretty humid. Get ready for that too. I'm going to have a car meet you at the airport, and it'll be $40 from JFK to Park Slope (you could take the subway, but it's a quality of life issue).
When you get here you'll put your stuff down and we'll walk around the corner for a slice of cheese pizza the size of a dinner plate which we'll eat as we wander the Brooklyn streets (which will, on a night like tonight, be packed with people).
I'm excited. You get pretend excited too.
