I'm Just Wild about Harry

I have finished the seventh & last Harry Potter book, and you are welcome to leave comments here. I'll start off with some of the ponderings I have had (either from the last book or from the series).

1) What do adult wizards/witches do for a living? We know that Mr. Weasley and Charlie work for the Ministry, that Bill works for Gringotts, that there are shopkeepers/bartenders, and there are teachers at Hogwarts. What does everyone else do? What did Harry's parents do? Indeed, what do the adult Harry, Ron, Hermione, & Ginny do?

2) Did you notice that Harry's parents and Nearly Headless Nick all died on Halloween?

3) How old is Hagrid? The second book said he was 13 when the Chamber of Secrets was opened, and then it was 50 years later when Ginny opened it. Then, the epilogue has them telling their kids (approx. 20 years later) to say hi to Hagrid at Hogwarts. Is he still Gamekeeper at approximated 83 years old? How old do giants live if they don't kill each other? His human father died fairly young.

4) Did George keep up with the Weasleys' Wizard Wheezes, or did he find that the inspiration and success came from both of them, so it went down the tubes after Fred died?

5) Did Kreacher continue to serve Harry and his family? If Kreacher died from old age, would Harry have replaced him? According to Dobby, Winky, & Kreacher, they are descendants of house elves who have always served their respective families. How do house elves meet and breed anyway? Do they have house elf bars or dance clubs?

6) Must you be single to be a professor at Hogwarts? Dumbledore, McGonagall, Snape, Trelawney, Sprout, Flitwick, etc. never mentioned going "home" at the end of the day. Indeed, do they sleep in their offices?

7) What parent would name his son Albus Severus? (And wasn't it obvious his other two kids would be named after his parents?)

8) Where do Harry and Ginny live - in #12 Grimmauld Place?

9) Did Harry, Ron, Hermione, and the others return to Hogwarts for that NEWT year, to finish their studies and earn their degrees?

Those are a few to start with. I might think of more questions later.
