HP passage for wedding

A friend of a friend wants to have a passage from one of the Harry Potter books read at her wedding, and my friends has turned to me for guidance. I'm immediately coming up blank, although I am at work without access to the books to help me. That said, I expect that many of you are likely better suited for this task than I, so... Thoughts? Suggestions?

There is the section where our heroes are discussing Harry kissing Cho, or the lovesick Tonks whose patronus has gone all wacky, or Lavendar cooing over Ron. There also might be something in Harry's speach to Lupin after he ran out on Tonks. Lots of good ones.

Look at the final scenes of each book. They often contain reflections from Dumbledore about friendship and other possibly relevant topics.

Thanks, y'all!

Also, maybe there's something in the scene in the last book in which Harry is temporarily "dead" and talking to spirit-Dumbledore?

From JK herself, I believe:  "Love is the greatest power there is."

Also: "You are protected, in short, by your ability to love!"

It is our choices, Harry, that show what we truly are, far more than our abilities.
