The pictures don't do it justice. Kids were sorted into houses, wands were made, Potter mafia was played (Calvin and I were Dobby; Lucy was a member of the order of the Phoenix), house points were earned by hunting for hidden objects and playing Potter trivia--and the peanut butter filled chocolate frogs were enjoyed by all!
(Lucy went as Hermione, Calvin as "a dinosaur" aka a dragon or a basilisk, depending on when you asked him, and I went as Nagini. I wore that snake around my neck all night!)
