She also saved 2 of them, her favorites, as keepsakes. She treasured these rocks. In June, a friend of mine came for a visit from South Africa and stayed with us for a few days. When he was going to leave, Nadia told him she had a present for him, and I was surprised to see that she was giving him one of the word rocks that she had saved. More recently, another friend came over to visit from Mexico City, and Nadia shared with him the last rock that she was saving.
