David, upon hearing the news, grabbed the nearest pillow and began flailing it at Michael, his best friend. "You're leaving me!" he shouted, his voice muffled slightly by the pillow. He then began jumping around the room, as if he couldn't sit still for a second.

He stopped, catching his breath, and then pointed dramatically at Michael. "Do you realize what this means? We'll have to cram all the things we've always talked about doing into these next few weeks!"

He started listing off a series of increasingly absurd plans - a marathon video game session, a road trip to the grocery store five towns over, and building a tree fort. He was going to make sure that they had a blast before Michael left.
