My Awesome Sister (tm) sent me this link today. I added the Post Secret site to my list of links, but I love this presentation as well. It's a bit lengthy, but worth it.
Here's some truth: I've still got two voicemails that my grandmother left me over a decade ago. She's still alive, but she has never called me that much so I've kept them. One is her singing me happy birthday and relaying birthday wishes from her and my grandfather (who died in 2006). This made me go listen to them again. Good times.
I also have a voicemail from my neighbor circa 2002 letting me know that my cat had gotten locked outside by mistake. Said cat is freaking out in the background, which is pretty hilarious. That feisty grimalkin passed away last year, so I guess I do have a voicemail to remember the dead.
