Adam: A top-notch birthday celebration.
Caitlin: Textbooks. You pay an arm and a leg for them. Then you try to sell them back at the end of the semester and they're all like "Yeah, we're changing editions. We can only give you $5 for that book you paid $150 for three months ago."
Adam: Having no motivation to study for finals!
