In the Harry Potter books, which parts made you cry the most?

I think I only cried once or twice while reading it, possibly three. I think I cried after Dumbledore died when they were at the funeral and also might have when Doby died. The one place I know for sure I cried was when Harry was walking to the forest getting ready to give himself up and is seeing everyone as he pes by, invisibly, and sees his parents.
