Hagrid is the only voice that is not convincing enough for my Boy when I read. I do a passable Harry Potter, Ron Weasley, Draco Malfoy and I can even get that bit of ‘tude in Hermoine’s delivery (in the first book). I like Dumbledore, but struggle a little with Snape - but then again, we’re talking about Alan Rickman, so what can you do? His voice is so unique and his delivery nearly impossible to match.
The Boy’s favorite voice that I do is that of the Sorting Hat. When Susan Bones is called before the school to be sorted and the Sorting Hat yells, “Hufflepuff!” my boy giggled and said, “Say it again, dad!” He then settled down so we could get to Harry’s part. He sat in great anticipation (even though he knew the outcome) of what fate the Sorting Hat would lay out for Harry. And when I read, “Better be… GRYFFINDOR!” he let out a little “Yes!”
Books rock.
