Is there a song or part of a movie or park that makes you cry every time? I have two, when Mufasa dies in the Lion King and Simba has that helplessness about him and tells his daddy to "wake up". Holy cow!
and when my daughter (4) and I sing the "At last I see the Light" song from Tangled. If I can have that be the first dance at her wedding between her and her husband, my heart will probably explode!
