The worry stone

My well-travelled niece is currently in Leichtenstein, which is near Switzerland and Austria. You can actually bike a route that takes you through all three countries in half an hour. In spite of this, the Leichtensteinians are loudly and proudly NOT Austrian or Swiss (and especially not German). She sent me a present and tells me that it's a worry stone, actually she says it's a wowwy stone. You hold it when you feel wowwied.
