I've finally been finishing my re-read of Deathly Hallows and have first-hand discovered what a completely horrible idea it is to start Chapter 29: The Lost Diadem at 6:20 in the morning, right before you need to go to work.

First I got all flaily about Neville's letter from Gran saying that he's his parents' son, and then Fred had a line. *bursts into tears* Oh Deathly Hallows, you hurt me, you hurt me so good.

And I think that's pretty much the last chapter I can read without going straight through to the end.
