Is this actually what she was writing all this time? That's a bit ridiculous if you think about it.
Every Monday morning, she'd need to read her diary to be able to 'remember' her friends. There's two flaws with this:
1. Most of the stuff she wrote was a bit long and pointless, with every entry taking up at least a page. As time goes on, she'd have to read more and more pages.
