I rarely re-read this book, because I have this weird thing about over-indulging in emotions through media cheapens both the media item in question and the emotions induced, but A Ring of Endless Light by Madeline L'Engle has never failed to make me bawl.

Also, a song called "Mein Berlin" by the German singer Reinhard Mey that is a beautiful, beautiful song-history about the division and reunion of Berlin. There's a bit near the end where he sings "Freiheit-- endlich Freiheit über meiner Stadt" (Freedom, finally freedom in my city) and his voice soars up over recordings of the crowds cheering at the Brandenburg Gate the night the Wall came down and even writing this has made me teary-eyed. But yeah. Same weird thing about not listening to it too often.
