I'd been working on my <a href="http://mattgemmell.com/index.php/dev/mac/icalendar.html">iCalendar class</a>
last night, and I was taking a break from Xcode to talk through the functionality with Fiona, discussing ideas.
She'd proposed a particular behaviour for the class, which I agreed with, and I thanked her for the input.
She then said: "You need me like your code needs <code>#import <Cocoa/Cocoa.h></code> at the top!"
