The situation

Lesson 1 gave you reminder_text(name, title, days_late). Ben has The War of the Worlds out on loan L13, 9 days late, so his reminder says he owes £1.80. Now Amira wants more. Tom hands out reminders on Saturdays, so some should be signed by him. She wants one function that totals the fees for however many loans she names. And she wants calls that are hard to get wrong, because a reminder with the title where the name should be is embarrassing.

All of that is about one thing: how values travel from a call into a function.
