Good Luck. And Take Care of Each Other(2012)

Original title: Lycka till och ta hand om varandra

Alvar is a pensioner who hides his guilt by "constructing" fictitious memoirs. By chance he meets Miriam, a socially tone deaf and obstinate teenager, and they become friends. Their friendship deepens when they begin to inspire downhearted people with public art, and comes to a head when they themselves have to blossom.
