Inspired by this heartbreaking post on tumblr--essentially about a girl and a boy who met on an elevator and could have had a wonderful relationship. Except that elevator was in one of the twin towers on September 11, 2001.
Oh goodness. Those lines ( "i love the smiths" "sorry" "i said i love the smiths" ) were from 500 days of summer. But I think this is lovelier and more touching because you can already understand the story in just a picture and short lines or 1mb gif than a 3hr movie XD
