i walked into Ollivander's. Not my first choice for wands, but the most convenient. I wanted a black glossy wand but Ollivander told me i should start with a mahogany wand. I thought it was the stupidest thing i had ever heard but i picked one up and swung it around. it blew up a chair.
"I told you that it wouldn't work old man!" I stalked back over to the shelves of ebony to find a better one. i found a nice one that was about 11 inches with unicorn hair. it was better but not great. it blew up a fish bowl. i slid another one off the shelf, this time, 11 3/4 inches with dragon heartstring. it was perfect! i picked it up and a fine layer of sand flew around and settled on everything.
"I'll take this one. But next time, don't question the ability of a Black."
