I really love this short film (12 minutes long) Signs by Australian director Patrick Hughes. It will be presented in the upcoming Schweppes Short Film Festival. The film has no dialog between the two main characters, just a soundtrack. Communication is done by signs, facial expressions and scrabbles on papers. The movie is pretty emotional, depressing and sweet at the same time. I highly recommend you watch it.
Signs is produced by Publicis Mojo and @RadicalMedia and if you like the soundtrack, you can get it here.
