Well, next think I knew, she had it all organized. She had made a list of nine games (she was sure to use plenty of alliteration in the titles: "Fantastic Fishing," "Reading Race," and so on...) and then laid out any materials we would need for each game. She explained the rules and then monitored everyone's compliance.

She made it really fun for everyone, including herself. That's pretty easy to do, especially if you appoint yourself judge and participant, because then you get to win every single time.
