Erica Wexler, who tragically died at a young age, still hops onto Facebook every now and then and chats with friends and family. The short touches on a few different scenarios that could explain the apparent communication from the dead, but ultimately the folks interviewed resign themselves and accept it, thinking that she's somehow influencing their lives. Yeah, real important influence, such as (and I'm paraphrasing) "Friend: Hey, should I get bangs? Erica: Yeah, totally". It's subtle, understated humor in a very original way.
