I've been reading Sheldon for years now - it is one of my favorite things to do every weekday when I get to work - but this storyline was so touching that I had to register so I could tell you that. It was beautiful. I love that about "film" cameras - how exciting/terrifying it is to find a camera full of half used up film and have no idea what is on there. It is something you never get to experience with digital cameras...
Plus, the end was perfect.
