Over the last 6 or so months, we've slowly been working out way through the Harry Potter series, reading a chapter or two out loud every before bed.
These two can often be found outside playing Harry Potter. I've seen them play quidditch while riding on rake handles, watched them fight the dragons in the Tri-Wizard Tournament, seen them sneak Snape some poisonous something or other, found them pouring over a Maurader's Map, and caught them pretending they had turn Draco into a White Ferret and were bouncing him all around the back yard a la Mad-Eye Moody.
It's been fun to see their imaginations at work and how they have brought the story to life through their own eyes.
Plus I have fun reading the stories and giving each of the characters voices. I think I do a pretty good impression of Hagrid and a fairly passable Alan Rickman inspired Snape. I just wish I could someone get a little more disdain in my voice. Where does Mr. Rickman hide it all??
