'Ruthie loves visiting her Oma. They always have lots of fun together. One day Ruthie finds a pretty tin while playing hide and seek at her Oma’s house. It’s full of Oma’s beautiful ‘memory buttons’ – each one reminds Oma of a special person in her life and a story to share with Ruthie. And of course Ruthie must have a memory button of her own!'
