Overview
Karla Geisler is a woman with her heart in the right place and a very quick mouth - the tenant on the first floor is practically the good soul of the entire building community. Karla is also the aunt of a 32-year-old single man called Karl, who is not lacking in imagination. Every Wednesday, he invites himself over to Auntie's for coffee and cake so that he can do some geological studies in peace.
