What type of pet do you choose as your companion at Hogwarts?
An owl, obviously! Do you have ANY idea how much money this would have saved me in college?
While shopping in Hogsmeade you stop by Honeydukes for some sweets. What treats do you purchase for yourself?
Dark chocolate. I might pick up a few chocolate frog cards, because I would probably have been collecting the cards since I was about seven, but other than that, Dark Chocolate and possibly some confection they have never described in the books that might somehow resemble a cross between Rugglach, Chocolate Croissants, Baklava and Biscotti.
A potion you are preparing needs an ingredient available only at muggle shops. You don't want to stand out in your wizards robes, so you resort to traditional muggle clothing. Describe your outfit in detail. This would really depend on what Muggle shops I have to go into. If we are talking the used-bookstore/hardwarestore/ethnic neighborhood foodstores then I would be wearing black jeans, leather shoes, a jewel-neck very thin knitted top in black, brown or green with a rust colored cabled sweater over it and carrying some huge, canvas-type bag. If it were an office supply/u[sacale stationer's store then I might get to wear a trim little Lois-Lane type suite with a small but excentric had, leather gloves and and a pair of pumps with indecently hight heels. However, most of the Muggle shopping I actually do is at Costco, the supermarket and the dollar store, and recent outfits have included a pair of lavender-blue fake crocs (2.99 at the dollar store) a green pink and white cotton print dress with an elasticized smocked top and tiered skirt that goes down past my knees, and a little black nylon bag I can just cram my little wallet, cellphone and camera into with difficulty and some compromise. I am usually wearing hanging earrings, rings on both hands, a charm bracelet, and frequently a pin, sometimes a crazy pin, and less often a necklace, which is way more jewelry than people in some parts of North America but much less than Professor Trelawney. I would not say I "Accessorize"with anything much except pins, although I do wear shawls pretty much when I want to and whether or not anyone else thinks they would go with my particular outfit.
What is your favorite subject to study at Hogwarts and why? Most favorite would probably be Ancient Runes, although I would probably also be fond of History of Magic, which I would probably cope with by doing all the reading, writing something totally unrelated while class was going on, and asking questions afterwards if I could get Binns to pay attention.
Likewise, what subject is your least favorite and why? I would not like Potions because I would stink at it, although I might very well like Snape as a professor - I tended to like the difficult ones. I have severe moral doubts about Transfiguration of/to living objects and so would probably butt heads with MacGonagall a lot.
Back to the potion you were shopping for ingredients for, what type of potion are you making, what color is it, what are the ingredients, and precisely what does the potion do? The potion I am making is striped a lime green, pink and teal, includes Osprey feathers, Wrackspurt scales and the reed from a clarinet among many many other ingredients. It enables one to dance, although not simply walk, upon the surface of the sea and certain large lakes. Used upon land, it turns one into a virtual Fred Astaire or Ginger Rodgers. (Tonks took some for her wedding and managed not to knock anything over all day...)
